Output capacity:

The efficiency rating of the appliance is a product thermal efficiency rating determined under continuous operating conditions and was determined independently of any installed system.

GAS CONNECTION

The gas connection is a 3/8" NPT rigid pipe. This pipe is supplied separately and must be in- stalled at the left rear of the unit. See page 2 for diagram. The gas line can be rigid pipe or to make installation easier, use a listed flexible connector and manual shut-off valve if allowed by local codes, or copper if approved. For minimum and maximum supply pressure see the System Data table.

Note: During any pressure testing of the gas supply piping system that exceeds test pressures of 1/2 psig, this appliance and its individ- ual shut-off valve must be discon- nected from the piping system. If test pressures equal to or less than 1/2 psig are used then this appliance must be isolated from the piping system by closing its individual manual shut-off valve during the testing.

HIGH ELEVATION

This unit is approved in Canada for altitude 0 to 4500 ft. (CAN1 2.17-M90) with the orifice sup- plied.

GAS PIPE PRESSURE

TESTING

The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig. (3.45 kPa). Disconnect piping from valve at pres- sures over 1/2 psig (14" w.c.).

The manifold pressure is controlled by a regu- lator built into the gas control, and should be checked at the pressure test point.

Note: To properly check gas pressure, both inlet and manifold pressures should be checked using the valve pressure ports on the valve.

1)Make sure the valve is in the "OFF" position.

2)Loosen the "IN" (# 7) and/or "OUT" (# 6) pressure tap(s), turning counterclockwise with a 1/8" wide flat screwdriver.

3)Attach manometer to "IN" and/or "OUT" pressure tap(s) using a 5/16" ID hose.

4)Light the pilot and turn the valve to "ON" position.

5)The pressure check should be carried out with the unit burning and the setting should be within the limits specified on the safety label.

6)When finished reading manometer, turn off the gas valve, disconnect the hose and tighten the screw (clockwise) with a 1/8" flat screwdriver. Screw should be snug, but do not over tighten.
