‡ Maximum Supply Gas Pressure

* Manifold Gas Pressure

3.5” W.C. (0.87 kPa)

10” W.C. (2.49 kPa)

‡Maximum supply pressure; readings are taken while gas is not flowing (static pressure) AND while gas is flowing (dynamic pressure). Supply pressure must never exceed this maximum value.

†Minimum supply gas pressure; readings are taken while gas is not flowing (static pressure) AND while gas is flowing (dynamic pressure). Supply pressure must never fall below the minimum values. Supply gas pressures should be measured with all gas fired appliances conencted to a common main firing at full capacity. If supply pressure drops more than 1.5” W.C. as gas begins to flow, the supply gas system (gas line/regulator) may be restricted or undersized. See the instruction manual for more information.

*Manifold gas pressure; reading can only be taken while gas is flowing. Reading taken should be ± 0.3” W.C. of the listed value. These water heaters are certified for use without modification for altitudes up to 10,000 feet. For elevations above 10,000 feet (3,048 meters), see High Altitude Installations section of instruction manual.

AIR REQUIREMENTS

Carefully review the requirements for combustion and ventilation air in the instruction manual that came with the water heater. Failure to meet these requirements when the water heater is installed or overlooking their importance when servicing the water heater often results in operational problems (some are listed below), needless down time, unnecessary parts replacement, and customer dissatisfaction.

Ensure additional air for combustion and ventilation is provided when additional gas fired appliances are installed to increase hot water supply in an existing location.

Air Supply

Stoichiometric or theoretical complete combustion requires 10 cubic feet of air per 1,000 BTUH of gas supplied. The National Fuel Gas Code also recommends an additional 2.5 cubic feet of “excess” air. For information on minimum make-up air opening sizes for various building installations, refer to the National Fuel Gas Code NFPA 54, ANSI Z223.1.
