Connect the Gas Line

Gas access holes are provided on both sides of the

ﬁrebox.

Check gas valve type. Use only the gas type indicated

on the gas log rating plate. If the gas listed on the plate

is not your type of gas supply, DO NOT INSTALL. Con-

tact your Dealer for the proper model.

Always use an external regulator for all LP ﬁreboxes to

reduce the supply tank pressure to a maximum 14" w.c.

This is in addition to the regulator ﬁtted to the vent-free

heater.

WARNING: Connection directly to an un-

regulated LP tank can cause an explosion.

For ﬁnal connection of the gas log heater to the gas

line, see Section 5 and Figure 6.

and the gas line.

Access to the gas line on the UV Series ﬁrebox is made

through the left or right side of the ﬁrebox. Locate the

appropriate gas line in the outer casing of the ﬁrebox

and remove the insulation from the gas line tube.

From the inside of the ﬁrebox, locate the knockout on

the ﬁrebrick - be sure you are on the appropriate or gas

line side of the ﬁrebox. Using a ﬂat- bladed screwdriver

or small chisel and hammer, carefully tap around the

knockout until it loosens and falls out.

2. Install the Vent-Free Gas Log Heater exactly as

described in the instructions for the heater. If for any

reason, you do not have these instructions, contact

your dealer or manufacturer for another copy.

NOTE: The gas line connection to the log set can be

made with properly tinned 3/8" copper tubing, 1/2" rigid

pipe, or an approved ﬂex connector. Because some mu-

nicipalities have additional local codes, it is always best

to consult your local authority.

U.S. INSTALLATIONS – Follow local codes and the

National Fuel Gas Code ANSI Z223.1/NFPA 54.

Always check for gas leaks with a mild

soap and water solution. Do not use an

open ﬂame for leak testing.

When using copper or ﬂex connector use only approved

ﬁttings. Always provide a union so that gas line can

be easily disconnected for burner or fan servicing. See

gas speciﬁcation for pressure details and ratings.

Cold Climate Insulation

In cold climates, insulation of the enclosure around the

ﬁrebox is suggested to avoid problems with cold air.

Insulating the enclosure around the ﬁrebox is recom-

mended, but not a requirement

The following steps are suggested to minimize cold air

problems.

Insulate the base of the ﬁrebox with a noncombustible

insulation. This step is particularly important for outside

wall installations over concrete slab ﬂoor construction.

If a platform is used to raise the ﬁrebox, the insulation

should be placed onto the platform before the ﬁrebox is

set. (Fig. 7)

Refer to Page 5, Figure 3 for minimum clearances to

combustibles.

Inspect joints of the ﬁrebox as well as the points of seal-

ing between the ﬁrebox and the ﬁnishing materials.

When a ﬁrebox is installed in a chase or on an outside

wall, the enclosure should be insulated like any other

outside wall of the home. Plywood or hardboard may

be placed on the standoffs and insulation placed on this

surface. (Fig. 8)
