Gas Meter Size
– Natural Gases Only
Be sure that the gas meter has sufficient capacity to supply the full rated gas input of the water heater as well
as the requirements of all other gas fired equipment supplied by the meter. If the gas meter is too small, ask
the gas company to install a larger meter with adequate capacity.
Gas Pressure Regulation
Main line gas pressure to the water heater should be between a maximum 14.0 inch W.C. and a minimum
supply pressure as shown on the rating plate. The inlet gas pressure must
NOT
exceed the maximum value.
In some installations, a regulator sized for the input rating of the water heater will need to be installed. Install in
accordance with the manufacturer for the regulator.
BEFORE PLACING THE WATER HEATER IN OPERATION, CHECK FOR GAS LEAKAGE. USE SOAP
AND WATER SOLUTION OR OTHER MATERIAL ACCEPTABLE FOR THE PURPOSE OF LOCATING
GAS LEAKS.
WARNING
Do NOT use matches, candles, flames, or other sources of ignition for this purpose.
