16 - MAINTENANCE
WARNING!!!
Never store
combustible materials, gasoline
or any product containing
flammable vapors and liquids
in the vicinity of the appliance.
Failure to comply with this
warning can result in extensive
property damage, severe
personal injury or death!
WARNING!!!
Never
obstruct the flow of combustion
and ventilation air. Failure to
provide adequate combustion
air for this appliance can result
in excessive levels of carbon
monoxide which can result in
severe personal injury or death!
WARNING!!!
If
maintenance is performed on
the vent-air intake system it
must be properly reassembled
and sealed. Failure to properly
maintain the vent-air system
can result in excessive levels
of carbon monoxide which can
result in severe personal injury
or death!
WARNING!!!
Before
performing any maintenance
operations, shut the appliance
off, close the manual gas
shut-off valve (Figure 13-1)
and shut electrical power off
to the appliance. Follow the
Operating Instructions outlined
in the Section "SAFETY
INSTRUCTIONS" (Page 3 of this
manual).
16.1.1 - Address reported
problems
Inspect any problems reported by the
owner and correct before proceeding.
16.1.2 - Check all piping
for gas leaks
1.- Inspect all gas piping and verify to
be leak free;
2.- Check for gas leaks: using soap
solution, check for gas leaks from
meter to appliance including all
pipes and fittings and appliance
connection. Use liquid soap solution
for all gas testing.
WARNING!!!
Do not check
for gas leaks with an open
flame. Use the bubble test.
Failure to use the bubble test
or check for gas leaks with
an open flame can cause
explosion, severe personal
injury, death, or substantial
property damage.
16.1.3 - Verify flue and air
lines in good condition
and sealed tight;
1.- Check for obstruction,
condensation, corrosion and
physical damage, water stains, any
signs of rust, other corrosions or
separation of the vent and air intake
piping;
2.- Check outside terminations.
Screens and louvers should be free
of any debris and must be cleaned
as required.
16.1.4 - Check system
water pressure/system
piping/expansion tank;
1.- Check water piping and
accessories for leaks. Slightest
leaks should be corrected;
2.- Check the system to be full of
water and pressure to remain stable
at correct setting on gauge.
CAUTION!!!
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.
16.1.5 - Check control
settings
1.- Set appliances setpoint low enough
to end call for heat. Gas valve
should close and burner should
103
stop firing; Fan will go into a post
purge, then shuts off;
2.- Control Safety Shutdown test: with
the burner firing, close the manual
gas shut off valve (Figure 13-1).
Gas valve should close and burner
should stop firing. The appliance
will try for ignition five times, then
should lock out with a "Loc 1" error
shown on the display. Open the
manual gas shut-off valve, and
verify your gas meter. Gas flow must
be zero;
WARNING!!!
If gas flow
occurs, close the manual gas
shutoff valve and troubleshoot
the system to determine why
there is gas flow when the gas
valve should be deenergized. Do
not operate the appliance until
the problem is resolved or a fire
or explosion causing property
damage, personal injury or loss
of life may occur!
3.- Press the "Reset" key to return to
normal operation.
16.1.6 - Check ignition
and flame sense
electrodes
1.- Remove the fan-burner assembly
unit (see Section 16.3);
2.- Remove any deposits accumulated
on the ignition/flame sense
electrode using sand paper;
3.- Check electrodes positioning meet
Section 16.4.
16.1.7 - Check wiring and
connections
Inspect all appliance wiring, making
sure wires are in good condition and
securely attached.
16.1.8 - Perform
performance verification.
1.- Run the unit at maximum input
following Section 14.9. When in
steady state, check the efficiency
using as per recognized methods.
Efficiency shall be not less than
88%;
2.- Verify cold water pressure is
correct and that operating pressure
does not go too high (could be a
problem on the expansion tank).
