INSTALLATION INSTRUCTIONS
Gas Supply Installation
Install the manual gas appliance shut-off valve to the
gas connection at the water heater. The shut-off is
supplied with the water heater.
Install a ground joint union or ANSI design-certified
semi-rigid or flexible gas appliance connector to the
open end of the manual gas appliance shut-off valve.
The NFGC, ANSI Z223.1 and CAN/CSA B149.1 codes
mandate the use of manual gas shut-off valve.
Install a manual gas supply line shut-off valve
to the end of the gas supply line.
Using the proper-size piping, fittings, and components,
build the gas supply line to the water heater.
NOTICE:
The gas supply line should be a minimum of 3/4-in. (1.9-cm)
black steel pipe or other approved gas piping material.
Install a sediment trap at the lowest portion of the gas
line.
The inlet gas pressure to the water heater must NOT
exceed 10.5 in. w.c. (2.6 kPa) for natural gas and
13 in. w.c. (3.2 kPa) for LP gas. For purposes of input
adjustment, the minimum inlet gas pressure (with main
burner on) is shown on the water heater rating plate. If
high or low gas pressures are present, contact your gas
supplier for correction.
