Follow the service and maintenance procedures given throughout this manual and in component literature
shipped with the appliance. Failure to perform the service and maintenance could result in damage to the
appliance or system. Failure to follow the directions in this manual and component literature could result in
severe personal injury, death, or substantial property damage.
The appliance should be inspected annually only by a qualified service technician. In addition, the maintenance
and care of the appliance designated in Table 2A and explained on the following pages must be performed to
assure maximum appliance efficiency and reliability. Failure to service and maintain the appliance and system
could result in equipment failure.
Electrical shock hazard – Turn off power to the appliance before any service operation on the appliance except as
noted otherwise in this instruction manual. Failure to turn off electrical power could result in electrical shock,
causing severe personal injury or death.
Address reported problems
1. Inspect any problems reported by the owner and correct
before proceeding.
Inspect appliance area
1. Verify that appliance area is free of any combustible
materials, gasoline and other flammable vapors and liquids.
Inspect appliance interior
1. Remove the outer access panels and inspect the interior of
the appliance.
2. Vacuum any sediment from inside the appliance and
components. Remove any obstructions.
Eliminate all system or appliance leaks.
Continual fresh makeup water will reduce
appliance life. Minerals can build up in
sections, reducing heat transfer, overheating
heat exchanger, and causing heat exchanger
failure. Leaking water may also cause severe
property damage.
1. Inspect all water and gas piping and verify to be leak free.
2. Look for signs of leaking lines and correct any problems
found.
3. Check gas line using the procedure found in the Gas
Connections of the Installation and Operation Manual.
Check all piping for leaks

Flue vent system and air piping
1. Check for gastight seal at every connection, seam of air
piping, and vent piping periodically inspected by a qualified
service agency.
Venting system must be sealed gastight
to prevent flue gas spillage and carbon
monoxide emissions, which will result in
severe personal injury or death.
ƽ WARNING
Combustion air filter
This appliance has a standard air filter located at the combustion
air inlet at the rear of the appliance. This filter helps ensure
clean air is used for the combustion process. Check this filter
every month and replace. The filter size on the 500,000 -
750,000 Btu/hr models is 12" x 12" x 1" and 16" x 16" x 1" on
the 990,000 - 2,070,000 Btu/hr models. You can find these
commercially available at any home center or HVAC supply
store. Do not use pleated filters.
Check water system
1. Verify all system components are correctly installed and
operational.
2. Check the cold fill pressure for the system. Verify it is
correct (must be a minimum of 12 PSI).
3. Watch the system pressure as the boiler heats up (during
testing) to ensure pressure does not rise too high.
Excessive pressure rise indicates expansion tank sizing or
performance problem.
4. Inspect automatic air vents and air separators. Remove
air vent caps and briefly press push valve to flush vent.
Replace caps. Make sure vents do not leak. Replace any
leaking vents.
Check expansion tank (if provided)
1. Expansion tanks provide space for water to move in
and out as the heating system water expands due to
temperature increase or contracts as the water cools.
Tanks may be open, closed, diaphragm or bladder type.
See the Water Connections Section of the Installation and
Operation Manual for suggested best location of expansion
tanks and air eliminators.
