The water heater and its manual gas
The water heater must be isolated from the gas piping system by closing the manual gas
3/8 psi (10.5” w.c.) for natural gas, or 1/2 psi (14” w.c.) for LP gas.
WARNING: Failure to install a water heater suitable for the altitude at the location it is intended to serve, can result in improper operation of the appliance resulting in property damage and/or producing carbon monoxide gas, which could result in personal injury, or death.
High Altitude
Input rating of this water heater is based on sea level operation. At higher elevations the actual input rate may be lower than the value listed on the rating label due to the derating of natural gas and LP gas. This water heater can be installed at elevation up to 2,000 feet without any change or modification.
For installation between 2,000 and 7,700 feet, refer to the Venting Information tables on page 13 and 14 for maximum vent lengths.
Installations above 7,700 feet are not authorized.
