Inspect/fill condensate system
Inspect/check condensate lines and fittings
1. Inspect the condensate drain line, condensate PVC fittings
and condensate trap.
Fill condensate trap with water
1. Remove the bezel as depicted in FIG. 8-1 on page 48 of this
manual.
2. Remove the PVC cap retaining screw from the PVC cap
(FIG. 10-1).
3. Remove the 2 inch PVC cap with the switch located at the
top of the trap (FIG. 10-1).
4. Fill with fresh water until the water begins to pour out of
the drain.
5. Replace the cap. Press the cap onto the trap until the cap
makes contact with the drain.
6. Replace the retaining screw.
7. Reinstall bezel.
⚠WARNING
The condensate trap (FIG. 10-1) must be
filled with water during all times of water
⚠WARNING
Clean/Inspect Trap Assembly
1. Remove the clean out cap on the bottom of the trap. Let the
condensate and any debris drain out.
2. Refill the trap according to the instructions above.
Check/control water chemistry
See the following table for properly operating the water heater
with the appropriate water chemistry. Good water quality will
help extend the life of the appliance by reducing the effects of
scale build-up and corrosion.
Check for gas leaks
Before starting the water heater, and during
initial operation, smell near the floor and

NOTICE
Conduct water quality testing prior
to installing the appliance. Various
solutions are available to adjust water
quality.

around the water heater for gas odorant or any unusual odor.
Remove the top access panel and smell the interior of the
water heater enclosure. Do not proceed with startup if there
is any indication of a gas leak. Use an approved leak detection
solution. Repair any leaks at once.
outlet pressure. This setting is suitable for natural gas and
propane, requiring no field adjustment. Attempting to alter the
gas valve outlet pressure could result in damage to the valve,
causing potential severe personal injury, death, or substantial
property damage.
1. Do not use the water heater to directly
heat swimming pool or spa water.
2. At initial fill and during water heater
start-up and testing, check system
thoroughly for any leaks. Repair all leaks
before proceeding further.
3. When water hardness levels are less
than 5 gpg or 85.5 mg/l, the following is
recommended:
a. Flush and clean existing water heating
system prior to installation.
b. Inspect and, if necessary, replace the
anodes in any existing tanks.
c. Install a Y-strainer on the inlet of each
water heater as detailed in Section 6.
d. Limit the run time of the hot water
recirculation loop.
e. Filter the hot water recirculation loop
to a level of 10 microns. CAUTION:
Check recirculation pump size to verify
it is sized for filter addition and upsize if
necessary.
4. When water softener is required, a
Template Assisted Crystallization system
is recommended.
to make its presence detectable. In some instances, the odorant
can fade, and the gas may no longer have an odor. Before
startup (and periodically thereafter), have the propane supplier
verify the correct odorant level in the gas.

drain line. Failure to fill the trap could result in severe personal
injury or death.
