LP-454 REV. 1.6.15
Do not install the water heater in a well, stairwell, alcove, courtyard, or other recessed area.
Do not install the water heater on stack frames.
In areas where heater is exposed to sustained temperatures below 32
o
F, provisions must be made to protect the water heater,
condensate lines, and piping from freezing. The use of heat tape is recommended to avoid freezing. It is also recommended to
bush up the condensate line size to 1” and terminate condensate discharge as close to the unit as possible. Longer
condensate runs are more prone to freezing.
Locate heater at least 10’ away from any forced air inlet. Maintain a clearance of at least 48” below or horizontal from any
window, door, walkway, or gravity air intake. Never place heater under a porch.
In areas where it can get extremely hot (over 100
o
F), it is recommended to install the heater in an area that avoids direct
sunlight to keep the internal components cooler. Failure to follow this instruction could lead to premature heater failure. Such
failures ARE NOT covered by warranty.
2. Check for nearby connections to:
System water piping
Venting connections
Gas supply piping
Electrical power
Condensate drain
3. Check area around heater. Remove any combustible materials, gasoline, and other flammable liquids.
When installing the heater outdoors, ensure the installation location is not near the exhaust or intake terminations of other gas-fired
products – boilers, water heaters, furnaces, etc. Failure to do so could result in the recirculation of exhaust fumes. Exhaust recirculation
could result in a hazardous condition and cause substantial property damage, severe personal injury, or death.
Failure to keep heater area clear and free of combustible materials, liquids, and vapors can result in substantial property damage,
severe personal injury, or death.
4. Gas control system components must be protected from dripping water during operation and service.
5. If the heater is to replace an existing heater, check for and correct any existing system problems, such as:
System leaks
Location that could cause the system and heater to freeze and leak.
Incorrectly-sized expansion tank
6. Clean and flush system when reinstalling a heater.
NOTE: When installing in a zero clearance location, it may not be possible to read or view some product labeling. It is recommended to
make note of the heater model and serial number.
B. LEVELING
In order for the condensate to properly flow out of the collection system, the area where you locate the heater must be level. Location
must also fully support the weight of the filled water heater. Failure to properly level the heater could result in improper heater operation,
premature product failure, property damage, personal injury, or death.
C. CLEARANCES FOR SERVICE ACCESS
All water heaters eventually leak. It is recommended to install a catch pan beneath the water heater. This catch pan should be sized
with a maximum depth of 2”, and a minimum diameter 2” greater than the diameter of the water heater. The catch pan should empty
into an open drain line. This drain line should be ¾” ID minimum, piped to an open drain. Failure to follow these instructions could result
in property damage. Such damages ARE NOT covered by product warranty.
