Connect the Gas Supply Line

UVS27 Vent-Free Gas Heater

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 appliance should have a main gas valve provided in an accessible location for turning on or shutting off

the gas to the main burner.

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

The UVS27 and its individual shutoff valve must be disconnected from the gas supply piping during any pressure testing of that system at test pres- sures in excess of 1/2 psig (3.5 kPa).

The UVS27 must be isolated from the gas supply piping system by closing its 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 28,000 BTUs at a manifold pressure of 3.5” and minimum 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 28,000 BTUs at a mani- fold pressure of 11.0” and minimum inlet supply for adjustment of 11.0” w.c.

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 you local authority.

Connect the gas supply and test for leaks. Use a 50/50 solution of liquid soap and water to test for leaks at gas ﬁttings and joints. NEVER test with an open ﬂame.

Light the pilot according to the directions on Psage 17, before going to the next step.

CAUTION

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

The UVS27 and its individual shutoff valve must be disconnected from the gas supply piping dur- ing any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).

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

In order to connect Natural Gas, use a ﬁtting with 1/2” NPT on the valve side and 1/2” natural gas supply line with an input of 28,000 BTUs at a manifold pressure of 3.5” between minimum inlet supply of 5.5” w.c. and maximum of 14.0” w.c.

In order to connect Propane, use a ﬁtting with 1/2” NPT on the valve side and 1/2” propane gas sup- ply line with an input of 28,000 BTUs at a manifold pressure of 11.0” between a minimum inlet sup- ply of 11.0” w.c. and maximum of 14.0” w.c.

Install Log Set

1.Remove the logs from their packaging, and inspect each piece for damage. DO NOT INSTALL DAM-

AGED LOGS.

2.Install the rear log by placing it on the sheet metal shelf at the back of the ﬁrebox. (Fig. 17) The log should touch the back wall of the ﬁrebox and be centered.

3.Install the right log by placing it on the sheet metal bracket behind the grate with the right end of the log, “the thicker end”, touching the grate and the right side the ﬁrebox. Swing the left end of the log “paint- ed end”, backward until it comes in contact with the branch on the rear log. Set the log down over the bent tab on the right. When the log is in place it rests on the tab mentioned earlier and the tip of it comes in contact with the branch on the rear log. (Fig. 17)
