Smoking can decrease your
ability to smell. Being around an odor for a time can affect your
sensitivity or ability to detect that odor. Sometimes other odors
in the area mask the gas odor. People may not smell the gas odor
or their minds are on something else. Thinking about smelling a
gas odor can make it easier to smell.
For example, if there is an underground leak, the
in LP-Gas also are subject to oxidation. This fading can occur if
there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into walls,
masonry and other materials and fabrics in a room. That will take
some of the odorant out of the gas, reducing its odor intensity.
LP-Gas may stratify in a closed area, and the odor intensity could
vary at different levels. Since it is heavier than air, there may be
more odor at lower levels. Always be sensitive to the slightest gas
odor. If you detect any odor, treat it as a serious leak. Immediately
go into action as instructed earlier.

Unvented gas heaters are a supplemental zone heater. They are not
intended to be a primary heating appliance. Water vapor produced

annoying smoke and smells as they are burned off during the initial
operation of the appliance; possibly causing headaches or eye or
lung irritation. This is a normal and temporary occurrence.
The initial break-in operation should last 2-3 hours with the burner
at the highest setting. Provide maximum ventilation by opening
windows or doors to allow odors to dissipate. Any odors remaining
after this initial break-in period will be slight and will disappear
with continued use.

Water vapor is a by-product of gas combustion. An unvented room
heater produces approximately one (1) ounce (30ml) of water for
Unvented room heaters must be used as supplemental heat (a
room) rather than a primary heat source (an entire house). In most
supplemental heat applications, the water vapor does not create a
problem. In most applications, the water vapor enhances the low
humidity atmosphere experienced during cold weather.
The following steps will help insure that water vapor does not
become a problem.

codes allow copper tubing or galvanized.
Since some municipalities have additional local codes, it is
always best to consult your local authority and installation code.
Each appliance should have its own manual gas cock.
A manual main gas cock should be located in the vicinity of the
unit. Where none exists, or where its size or location is not ad-

relocation.
Compounds used on threaded joints of gas piping shall be resistant
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required
by the National Fuel Gas Code that a drip line be installed near
the gas inlet. This should consist of a vertical length of pipe tee
connected into the gas line that is capped on the bottom in which
condensation and foreign particles may collect.
The use of the following gas connectors is recommended:

The above connectors may be used if acceptable by the authority

2. The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of
1/2 psig (3.5 kPa).
3. The appliance 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
pressures equal to or less than 1/2 psig (3.5 kPa).
If one of the procedures results in pressures in excess

1. Clean the ODS pilot by loosening nut B from the pilot tubing.
When this procedure is required, grasp nut A with an open end
wrench.
2. Blow air pressure through the holes indicated by the arrows.
This will blow out foreign materials such as dust, lint and
spider webs. Tighten nut B also by grasping nut A.

Thermostats are not approved on vented decorative appliances.
Label all wires prior to disconnection when servicing controls.
Wiring errors can cause improper and dangerous operation. Verify
proper operation after servicing.
The millivolt gas valve does not require 24 or 110 volts. The gas
valve is powered by the thermopile. See Figure 16 to provide
optional wall switch, thermostat, or remote control. Maximum
length of 20 feet of 16 AWG to conductor wires is to be used with
all optional switches.
Use the red and green leads from the rocker switch that are wire
nutted together to attach optional components.
Millivolt system and all individual components may be checked
with a millivolt meter 0-1000 MV range.
Use the following steps to place the adjacent to
the gas valve.
1. The remote receiver can not be placed behind the gas valve and
burner assembly.
2. When facing the appliance, the remote receiver must be placed
to the of the gas valve and burner assembly.
Do not let remote control receiver come in contact with

Refer to remote control installation and operating instructions for
more details on remote control.
When you ignite the pilot, the thermocouple produces millivolts
(electrical current) which energizes the magnet in the gas valve.
After 30 seconds to 1 minute time period you can release the gas
operate an additional one (1) to two (2) minutes before you turn the
gas control knob from the PILOT position to the ON position. This
time period allows the millivolts (electrical current) to buildup to a
The valve regulator controls the burner pressure which should be
checked at the pressure test point. Turn captured screw counter
