DISCONNECT THE HEATER AND ITS MANUAL GAS SHUTOFF VALVE FROM THE GAS SUPPLY PIPING SYSTEM DURING ANY SUPPLY PRESSURE TESTING EXCEEDING 1/2 PSIG (3.45 Kpa). GAS SUPPLY LINE MUST BE CAPPED WHEN DISCONNECTED FROM THE HEATER FOR TEST PRESSURES OF 1/2 PSIG (3.45 Kpa) OR LESS. THE APPLIANCE NEED NOT BE DISCONNECTED, BUT MUST BE ISOLATED FROM THE SUPPLY PRESSURE TEST BY CLOSING THE MANUAL GAS SHUTOFF VALVE.

GAS METER SIZE — NATURAL GASES ONLY

Be sure 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 gas meter is too small, ask the gas company to install a larger meter having adequate capacity.

not be less than 4.5" W.C. (1.12 Kpa) for natural gas and 11.0" W.C. (2.74 Kpa) for propane gas.

Do not subject the combination gas valve to inlet gas pressures of more than 14.0" W.C. (3.48 Kpa) - natural gas, 14.0" W.C. (3.48 Kpa) - propane gas. A service regulator is necessary if higher gas pressures are encountered.

Gas pressure specified in Table 5, refer to flow pressure taken at pressure tap of automatic gas valve while heater is operating.

GROUNDING INSTRUCTIONS

This water heater must be connected to a grounded metal, permanent wiring system; or an equipment grounding conductor must be run with the circuit conductors and connected to the equipment grounding terminal or lead on the water heater.

GAS PRESSURE REGULATOR

HEATER WIRING

The gas pressure regulator is built into the gas valve and is equipped to operate on the gas specified on model and rating plate. The regulator is factory adjusted to deliver gas to burner at correct water column pressure allowing for a nominal pressure drop through the controls.

The minimum gas supply pressure for input adjustment must

All electrical work must be installed in accordance with the latest version of the National Electrical Code ANSI/NFPA No. 70, and /or the CSA C22.1 Electrical Code, for Canada use Canadian Electrical Code CSA C22.1 and must conform to all local code authority having jurisdiction. AN ELECTRICAL GROUND IS REQUIRED TO REDUCE RISK OF ELECTRICAL SHOCK OR POSSIBLE ELECTROCUTION.
