Install Instructions

9 Start-up
Chlorine concentration less than 200 ppm
1. Do not fill the water heater or operate with water
containing chlorine in excess of 200 ppm.
2. Filling with chlorinated fresh water should be acceptable
since drinking water chlorine levels are much lower.
3. Do not use the water heater to directly heat swimming
pool or spa water.
4. At initial fill and during water heater startup and testing,
check system thoroughly for any leaks. Repair all leaks
before proceeding further.
Check for gas leaks
Before starting the water heater, and
during initial operation, smell near
the floor and 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.

 WARNING
 WARNING
Propane water heaters only – Your propane
supplier mixes an odorant with the propane
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.
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 PVC cap retaining screw from the PVC cap
(FIG. 9-1).
2. Remove the 2 inch PVC cap with the switch located at the
top of the trap (FIG. 9-1).
3. Fill with fresh water until the water begins to pour out of
the drain.
4. Replace the cap. Press the cap onto the trap until the cap
makes contact with the drain.
5. Replace the retaining screw.
 WARNING
The condensate trap (FIG. 9-1) must be filled
with water during all times of water heater
operation to avoid flue gas emission from
the condensate drain line. Failure to fill the
trap could result in severe personal injury
or death.
 WARNING
Final checks before starting the water
heater
 Read this manual to familiarize yourself with electronic
control module operation. Read pages 49 and 50 for proper
steps to start the water heater.
 Verify the water heater and system are full of water and all
system components are correctly set for operation.
 Verify the preparation procedures of Section 9, pages 47
and 48 have been completed.
 Fill the vent condensate trap with water (removing the
retaining screw in order to remove the 2 inch PVC cap with
the switch located at the top of the trap). Replace the cap.
Press the cap onto the trap until the cap makes contact with
the drain. Replace the retaining screw.
 Verify electrical connections are correct and securely
attached.
 Inspect vent piping and air piping for signs of deterioration
from corrosion, physical damage or sagging. Verify air
piping and vent piping are intact and correctly installed per
this manual.
Installation & Service Manual
DO NOT attempt to measure gas valve
outlet pressure. The gas valve is factory-
set for the correct outlet pressure. This
setting is suitable for natural gas and
propane (when configured for LP),
requiring no field adjustment. Attempting
to measure the gas valve outlet pressure
could result in damage to the valve,
causing potential severe personal injury,
death, or substantial property damage.
