Use and Care Manual
TO REMOVE BURNER TRAY:
1. Turn off manual gas shut-off valve.
2. Disconnect gas pipe union and wiring to gas valve, pilot, &
blower(If so equipped.).
3. Remove retaining screw or bracket from burner tray rail on side
opposite gas valve.
4. Slide burner tray assembly out. When reinstalling the burner
tray assembly, make certain it is pushed in all the way against
the stop attached to the bottom pan. Then reinstall the retaining
screw or bracket.
5. Reconnect gas pipe union and wiring to gas valve, pilot, and
blower(If so equipped), turn on manual gas shut-off valve and
test for gas leak.
B. VENTING SYSTEM — Inspect venting system at least yearly
to make certain the passageways are free and unobstructed, and
that the vent connectors from the water heater’s draft hood to the
chimney are properly positioned and securely attached. Remove
any obstructions in vent connector or chimney and replace any
corroded through vent connectors.
C. CONTROLS — The manifold pressure and controls should be
checked at least yearly by a qualified service technician.
D. BLOWER — Clean the blower periodically to remove any buildup
of lint or dirt. Remove the inlet plate and blow out any lint or dirt
on the wheel and on the screen of the inlet plate. Before operation,
re-install the inlet plate to the blower.
E. PRESSURE SWITCH — Inspect the inlet to the pressure
switch and the tubing for debris or blockage. Clean out the tubing
periodically to prevent buildup of debris.
1.This water heater is equipped with a combination thermostat/
temperature limiting device (ECO) that should be checked an-
nually by qualified service personnel.
Label all wires prior to disconnection when servicing controls. Wir-
ing errors can cause improper and dangerous operation.
VERIFY PROPER OPERATION AFTER SERVICING!
2. The Temperature and Pressure Relief Valve must be free to op-
erate properly. Check (at least once a year) by lifting the handle
fully and allowing several gallons of water to flush through the
discharge line. Make certain the discharged water is directed
to a suitable drain.
Before manually operating the relief valve, make certain no one
will be exposed to the danger of coming in contact with the hot
water released by this valve. The water may be hot enough to cre-
ate a SCALD hazard. The water released should be directed to a
suitable drain to prevent injury or damage.
NOTE: If the temperature and pressure relief valve on the water
heater discharges periodically, this may be due to thermal ex-
pansion in a “closed” water system. Contact the water supplier
or local plumbing inspector on how to correct this. DO NOT
plug the relief valve outlet.
D. TANK— Good maintenance requires that the tank be cleaned of
deposits. Unless the water supply is soft (0 to 5 grains hardness),
scale or lime deposits will accumulate in the tank. Hard water scale
is deposited at an increasingly high rate in proportion to increased
water temperature. Accumulation of these deposits may reduce
efficiency, and shorten the life of the water heater.
Any new installation should have a tank inspection program set
up initially for frequent inspection. The first inspection should be
within a six month period. Once the scaling tendencies have been
established, the inspection program can be modified to suit the
water conditions. Cleaning should be performed if the scale has
accumulated above the drain valve opening.
A wet-dry shop vac with a nozzle fashioned from 1” and/or 3/4”
polyethylene pipe makes a good tool for scraping and removing
scale.
TOCLEANORINSPECTTANK:
1. Shut off gas valve and drain tank.
2. Remove tank clean-out cover on jacket and with pocket knife
cut and remove a circular plug of insulation the full size of
jacket opening.
3. Loosen nut on seal plate assembly enough to twist yoke side-
ways. Hold assembly securely and push inward, then remove
