Check the rating plate attached by a steel cable to the firebox, to confirm that you have the appropriate firebox for the type of fuel to be used. The PDV20 and SDVR may be converted from one gas to another using the appropriate Fuel Conversion Kit listed on Page 41.

CAUTION

This appliance should only be connected by a qualified gas technician. Test to confirm manifold pressures as specified below.

The PDV20 and SDVR Heaters and the individual shutoff valves must be disconnected from the gas supply piping during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).

The PDV20 and SDVR Heaters must be isolated from the gas supply piping system by closing the individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressure equal to or less than 1/2 psig.

There must be a gas shutoff between the stove and the supply.

In order to connect Natural Gas, use a fitting with 3/8” NPT nipple on the valve side and 1/2” natural gas supply line with an input of 21,000 BTUs at a manifold pressure of 3.5” and mini- mum inlet supply for adjustment of 5.5” w.c.

In order to connect Propane, use a fitting with 3/ 8” NPT nipple on the valve side and 1/2” propane gas supply line with an input of 21,000 BTUs at a manifold pressure of 10.0” and minimum inlet supply for adjustment of 11.0” w.c.

In the U.S.: Gas connection should be made in accordance with current National Fuel Gas Code, ANSI Z223.1/NFPA 54. Since some municipalities have additional local codes, be sure to consult your local authority.

In Canada: consult the local authority and CSA-B149.1 installation code.

Connect the gas supply and test for leaks. Use a mild soap and water solution applied with a brush no larger than 1” (25mm). Never apply soap and water solution with a spray bottle. Do not use an open flame for leak testing.
