DO NOT
remove the factory installed exhaust/condensate elbow
for any reason, see Figure 11. The water heater’s vent pipe is
under a slight positive pressure while unit is in operation. The
water trap inside of the exhaust/condensate elbow prevents flue
gases from escaping into the installed space.
Do not install any external condensate trap. The exhaust elbow
assembly has an internal condensate trap.
CONDENSATE DRAIN INSTALLATION
Installation must conform with these instructions and local building
codes.
Field supplied materials required for installation include:
•
Approved PVC cement and PVC primer.
•
1/2 inch PVC pipe - minimum length to equal the distance
between the water heater and a suitable building drain.
•
1/2 inch PVC fittings (elbows, couplings, and adapters)
necessary to install a condensate drain line between the Exhaust/
Condensate Elbow Assembly and a suitable building drain.
•
Floor mounted standoffs to brace the drain line.
INSTALLATION NOTES
1.
The condensate drains from the water heater’s covered by
this instruction have PH levels between 4.3 and 5.0. Install a
commercially available neutralizing kit if required by local codes.
Lower PH levels are acidic. Do not connect a metal condensate
drain line, such as copper pipe, to the water heater for this reason.
2.
The field installed condensate drain line must not be less than
1/2 inch PVC in size.
3.
DO NOT remove, modify or alter the factory condensate trap.
INSTALLATION INSTRUCTIONS
1.
Ensure the water heater’s enable/disable switch is in the
“disable” position.
2.
Install a 1/2 inch PVC condensate drain line between
condensate drain connection on the Exhaust/Condensate
Elbow and a suitable building drain with a slight downward
slope to drain. The exhaust elbow has a “built in” condensate
trap. Do not install an additional trap in the condensate drain
piping. See Figure 12.
3.
Terminate the condensate drain piping with an elbow above the
drain. Ensure that any discharge will exit the condensate drain
line no more than 6 inches (15.2 cm) above a suitable building
drain, or external to the building, see Figure 11.
NOTE:
In cold climates it is recommended the condensate drain be
terminated at a suitable drain inside the building.
4.
Ensure the condensate drain line is not elevated above the
condensate drain connection on the Exhaust/Condensate
Elbow, see Figure 11.
5.
Brace the condensate drain line with floor mounted standoffs
every three feet.
6.
Ensure the condensate drains freely during start up and the
condensate clean out cap is on and tight when unit is in operation.
7.
Condensate clean out cap must be on and tight when unit is in
operation.
HIGH ALTITUDE INSTALLATIONS
This high efficiency water heater is certified for use
without modification for an altitude of 10,100 feet (3,078
m). Consult the factory for installation at altitudes over
10,100 feet (3,078 m).
Some gas utility companies derate their gas for altitude,
making it unnecessary to install high altitude orifices. Call
the local gas or utility company to verify BTU content.
Due to the input rate reduction at high altitudes, the output
rating of the water heater is also reduced and should
be compensated for in the sizing of the equipment for
applications.
FILLING THE WATER HEATER
Never use this water heater unless it is completely full of water.
To prevent damage to the tank, the tank must be filled with water.
Water must flow from the hot water faucet before turning ON gas
to the water heater.
To fill the water heater with water:
1.
Close the water heater drain valve by turning the handle to the
right (clockwise). The drain valve is on the lower front of the
water heater.
2.
Open the cold water supply valve to the water heater.
NOTE: The cold water supply valve must be left open when the
water heater is in use.
3.
To insure complete filling of the tank, allow air to exit by opening
the nearest hot water faucet. Allow water to run until a constant
flow is obtained. This will let air out of the water heater and the
piping.
4.
Check all water piping and connections for leaks. Repair as
needed.
