DV425TR DIRECT VENT ROOM HEATER

GAS LINE REQUIREMENTS

The gas line must be installed in accordance with all local codes, if any; if not, follow ANSI 223.1 and the requirements listed below.

The stove and gas control valve must be disconnected from the gas supply piping during any pressure testing of that system at test pressures in excess of 1/2 psig. For pressures under 1/2 psig, isolate the gas supply piping by closing the manual shut-off valve.

The appliance must be isolated from the gas supply piping system by closing its equipment shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.5 kPa).

Leak test all gas line joints and the gas control valve prior to and after starting the stove.

Fuel

This unit is manufactured for use with natural gas. To convert to LP gas, Part #844-9010 LP Conversion Kit, is required and available through your dealer

Gas Line Connection

Before making the gas connection, ensure that the stove you are installing is designed for the type of gas being supplied. This information can be found on the Ratings Label on the back of stove. If the stove has been converted to propane (LP), the valve cover will have a label stating that the unit has been converted to propane.

Connect the gas line at the 3/8” pipe connector on the valve at the back of stove. See illustration on the next page. We recommend connecting the stove with an approved flex gas line. If flex gas lines are not approved in your area, you cannect a hard pipe to the gas hookup.

You must supply a manual shutoff valve in a visible location within 3’ (914mm) of the stove.

After running new gas line, or if a gas line has been disconnected, purging of the gas line may be necessary. To purge gas line, open the inlet pressure tap and allow gas to flow through while carefully

monitoring for the odor of either natural gas, which will rise, or propane, which will settle near the floor. As soon as you smell the gas, discontinue purging the line. Ensure that the room has plenty of ventilation and that no sparks or open flames are near the end of the gas line during the purging process. Do not try to ignite the stove until any and all gas accumulation has been cleared from the room.

CAUTION: In some areas, gas line pressure may be more than 1/2 PSIG (14”WC). If you believe that this is the case in your locality, contact your gas supplier or local utility company. Line pressure greater than 1/2 PSIG will damage the stove valve. You must install a regulator upstream from the stove if line pressure is greater than 1/2 PSIG.
