36 Annual startup
The boiler should be inspected and started
annually, at the beginning of the heating
season, only by a qualified service technician.
In addition, the maintenance and care of
the boiler designated in Figure 111, page 85
and explained on the following pages must
be performed to assure maximum boiler ef-
ficiency and reliability. Failure to service and
maintain the boiler and system could result
in equipment failure.
Electrical shock hazard — Turn off power
to the boiler before any service operation on
the boiler except as noted otherwise in this
instruction manual. Failure to turn off elec-
trical power could result in electrical shock,
causing severe personal injury or death.
Address reported problems
1. Inspect any problems reported by owner and correct before
proceeding.
Inspect boiler area
1. Verify that boiler area is free of any combustible materials,
gasoline and other flammable vapors and liquids.
2. Verify that air intake area is free of any of the contaminants
listed on page 6 of this manual. If any of these are present
in the boiler intake air vicinity, they must be removed. If
they cannot be removed, reinstall the air and vent lines per
this manual.
Inspect boiler exterior
1. The boiler door, panels and aesthetic parts can be cleaned
with a soft damp cloth, possibly soaked in soapy water. Do
not use any abrasive detergents and solvents.
Inspect boiler interior
1. Remove jacket door and inspect interior of boiler.
2. Vacuum any sediment from the inside of the boiler and
components. Remove any obstructions.
Do not use solvents to clean any of the boiler
components. The components could be damaged,
resulting in unreliable or unsafe operation.
Check all piping for leaks
Eliminate all system or boiler leaks. Continual
fresh make-up water will reduce boiler life. Miner-
als can build up in the heat exchanger, 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 in the system and in the boiler
and correct any problems found.
3. Check gas line for leaks, see page 80 for gas safety informa-
tion.

Check ignition wiring
1. Check ignition cable electrical resistance. A good cable will
have resistance between 950 and 1050 ohms. Replace if not
acceptable.
2. Inspect boiler ground wire from heat exchanger access cover
to ground terminal screw.
3. Verify all wiring is in good condition and securely attached.
4. Check ground continuity of wiring using continuity meter.
5. Replace ground wires if results are not satisfactory.
Check all boiler wiring
1. Inspect all boiler wiring, making sure wires are in good condi-
tion and securely attached.
2. Verify that all connectors are securely inserted.

1. Use the
settings. Adjust settings if necessary.
2. Check settings of external limit controls (if any) and adjust
if necessary. Adjust as needed to accommodate the system
design.
Perform startup and checks
1. Start boiler and perform checks and tests specified in this
manual.
2. Verify cold fill pressure is correct and that operating pressure
does not go too high. Adjust water pressure and expansion
tank charge pressure as necessary.
3. Complete the check-out procedure on page 84.
Check burner flame
The boiler contains ceramic fiber materials. Use
care when handling these materials per instructions
on page 86 of this manual. Failure to comply could
result in severe personal injury.
1. Inspect flame through observation window.
