At Lamprey Energy, we believe that our customers’ peace of mind is key… knowing you have the right equipment and that it’s fully maintained in best possible condition is fundamentally important to us. Not only is well-maintained equipment more reliable, but also it is more efficient and lasts longer. That’s why we encourage all our service customers to sign up for a Service Plan with annual Preventive Maintenance procedure.
- Track your annual service month
- Preschedule your annual service
- Send a postcard with the date and time of your service
- Call two days ahead to remind you
- And, if the date is inconvenient, reschedule to suit you.
We remember so you don’t have to!
PREVENTIVE MAINTENANCE PROCEDURE
Oil boiler/furnace We pride ourselves on the professionalism of all our staff. When a service technician works at your property he takes care to protect it; he will leave the work area as clean as, or cleaner than, it was when he arrived. We use tarps and plastic cling carpet runners to protect your floors. Booties or socks are used when a technician walks through your finished space. When servicing or replacing oil filters, pumps, or oil line fittings, spill pads are placed beneath drip pans or trays to prevent stains and reduce odors. All our technicians carry Speedy-Dry and odor powder on the truck. When a Lamprey Energy service technician arrives on your property he will introduce himself and ask if you have experienced any problems with your system or if you have any questions. If he is unable to answer any question he will contact the office and either have the answer for you before he leaves, or make sure you receive it as soon as possible. For the preventive maintenance the technician will:
- Test fire the unit to be sure it is in operating condition before he starts.
- Turn off the service switch to kill the power.
- Visually inspect the unit.
- Check the oil tank:
- How much fuel is in the tank?
- What is the condition of the gauge?
- Is the tank at least 5ft from the burner or other sources of heat?
- What is the condition of the legs, pads, foundation?
- Is there any evidence of corrosion, oil spills, or leaks (old or new)?
- Are all unused openings properly plugged?
- Perform an ultrasonic tank test (if you have the Lamprey Energy TankSure® Plan).
- Check the fill pipe:
- Is it in good condition?
- Is the fill cap in place and in good condition?
- Check the vent pipe:
- Is the cap in place and in good condition?
- Is the vent unobstructed?
- Is the pipe the same size or larger than the fill pipe?
- Check the oil line:
- Is the oil line free of dents and kinks?
- Is it directly buried in cement or encased?
- Are the fittings all leak free?
- Are there any compression fittings? If there are, they will be replaced.
- Inspect the oil filter mechanism:
- Shut off the oil valve and make sure it is in good operating order.
- Replace the oil filter – preferably with a Garber filter.
- Lubricate the oil filter gasket with the recommended oil.
- Inspect the oil pump mechanism:
- Replace the oil pump strainer.
- Set the pump pressure at the recommended specification and check the pump cut off to be sure it holds pressure.
- If the tank is gravity-fed, bleed the line by opening the valve or line, and run it until the oil is clean and clear.
- Inspect the nozzle and firing assembly:
- Check the nozzle type, size, and spray angle against recommended specification.
- Remove the nozzle, drain the oil, inspect the nozzle adapter, and replace if required.
- Inspect the burner motor, housing, and fan:
- Remove the motor and check the burner housing for oil—this could indicate a loose fitting or cracked flare on the fuel pump seal.
- Check the burner coupling and replace as required.
- Clean the fan wheel.
- Lubricate the motor as required.
- Check that the cooling slots are clear.
- Check the motor shaft for end play and replace as required.
- Clean the air inlet and fan.
- Check the condition of the motor.
- Reinstall the motor and ensure everything is spinning freely and that all wires are connected.
- Inspect the transformer and cad cell:
- Clean and check the transformer bushings and springs.
- Inspect the ignition wires.
- Clean the cad cell eye and wires.
- Ensure the cad cell bracket is correctly positioned for a good flame sighting.
- Ensure the electrodes are making solid contact with the transformer springs and that no wires are being crimped.
- Inspect and clean the flue pipe:
- Remove the flue pipe and brush it out.
- Inspect the pipe’s condition and replace as necessary.
- Check the draft regulator.
- If the unit has a stack relay the helix and relay contacts will be inspected and cleaned.
- Clean out the chimney base and check for any obstructions.
- Ensure the smoke pipe has three screws per joint
- Clean the heat exchanger and combustion area:
- Remove the baffles, scrub the flue passages, check for signs of air or water leaks.
- Clean the combustion area.
- Inspect the refractory material and repair or replace as required.
Once the maintenance has been completed the technician will reassemble the unit using furnace cement, silicone, or Kaowool if required to seal any air leaks. He will double check the flue pipe and other items, including the filter and fuel pump, for leaks. He will then: Fire the unit and check operation:
- Start the burner, check the appearance of the flame, and make sure there is no impingement.
- Cycle the burner on and off several times to check prompt ignition, smooth operation, and clean cut-off.
- Keep the burner running in order to check the operation of the high limit.
- Conduct an efficiency test and make adjustments.
Preventive maintenance on some systems will also include some or all of the following, depending on the level of coverage purchased.
- Antifreeze system
The antifreeze will be tested. We use a refractory meter to test the freeze point of the antifreeze; the PH level will be tested for the acidity level—where the level is caustic we will recommend complete antifreeze replacement.
- Zone valves and circulators
The operation of all zone valves and circulators will be checked; the circulator motors and bearing assembly will be lubricated; circulator couplings and motor mounts will be checked for leaks; expansion tank and fittings, air scoop, and hi-vents will be inspected.
- Warm air system
The blower compartment will be cleaned. If necessary the blower will be lubricated. The tension and condition of the belt will be checked; the blower mountings and bearings will be checked; the filter will be replaced; the blower limit settings will be checked.
The humidifier operation will be inspected for water leaks and mineral build up; the condensate drain will be checked for blockage.
- Steam boiler
The low-water cutoff and automatic water feeder will be checked; the sight glass will be cleaned or replaced as required; the vents will be checked and inspected for evidence of leaks.
- Power venter
The motor will be inspected, lubricated, and cleaned. All vent connections will be inspected and connections will be replaced, sealed, or tightened as required. The venter choke plate and barometric damper will be checked. With the heating system in operation the pressure sensing tube will be disconnected from the power venter safety switch: this should shut off the burner—reconnecting should relight the burner. Following the maintenance and efficiency testing the technician will clean up and let you know of any concerns or issues that might require additional work. The office will follow up with pricing and, with your approval, to schedule the recommended work. The technician will leave you a work order detailing work carried out, parts replaced, and hours spent. back to top
