Greater than 3" *
*Any barrier greater than 3" placed in front of the gas log set is not
recommended by the manufacturer.
NOTE: Non-combustible material such as refractory brick
may be used to line the oor of the replace in order to raise
the height of the gas log set in relation to a restrictive barrier.
If the unit is raised, the minimum height dimension listed
in the homeowner’s manual must be met or exceeded.
NOTE: If the log set is equipped with a remote receiver, a
restrictive barrier may reduce the battery life by increasing
the ambient temperature inside the replace. Placement
of the receiver outside of the replace will extend the
battery life.
Barriers such as the bottom of a glass door frame
placed in front of a gas log set can change the air
ow characteristics of the replace which in turn
can cause the unit to overheat and malfunction when
installed as a vented log set.
WARNING
Glass door frames with adjustable louvers
should have the louvers fully open while
the unit is in operation
Depth of replace/rebox
(Refer to table)
The log set should be placed against

WARNING
F. Millivolt Ignition Controls
Natural Gas: An external regulator is required to reduce
supply pressure to a maximum of 10-1/2” w.c. on natural
gas systems operating at higher pressure.
The piezo ignitor allows ignition of the pilot without the use
of matches or batteries.
Milivoit control has four (4) positions:
OFF: All gas to the gas logs is shut off at the valve.
IGN: Valve position to light/maintain a standing pilot.
ON: Valve position to turn ON/OFF log set with remote
switch/thermostat.
LOW/HI: Variable position to control ame height (heat
output).
The gas log heater is tted with a specially designed safety
pilot (ODS assembly) which senses the amount of oxygen
available in the room and shuts the gas log heater off if the
oxygen level begins to drop below a satisfactory level. The
pilot can only be relit when adequate fresh air is available.
G. Pilot/ODS
Monessen • Glow Getter Owner’s /Installation Manual • 4606-900 Rev. A • 8/178
H. Adequate Combustion Ventilation Air
This heater shall not be installed in a conned space or
unusually tight construction unless provisions are provided
for adequate combustion and ventilation air.
The National Fuel Gas Code, (ANSI Z223.1/NFPA54),
denes a conned space as a space whose volume is less
than 50 cubic feet per 1,000 BTU per hour (4.8m
3
per kw)
of the aggregate input rating of all appliances installed in
that space, and an unconned space as a space whose
volume is not less than 50 cubic feet per 1,000 BTU per
hour (4.8 m3 per kw) of the aggregate input rating of all
appliances installed in that space. Rooms communicating
directly with the space in which the appliances are installed,
through openings not furnished with doors, are considered
a part of a conned space.
Unusually tight construction is dened as construction
where:
a. Walls and ceilings exposed to the outside atmosphere
have a continuous water vapor retarder with a rating of
1 perm (6 x 10
11
kg per pa/sec-m2) or less with openings
gasketed or sealed, and
b. Weather stripping has been added to windows and
doors, and
c. Caulking or sealants are applied to areas such as joints
around window and door frames, between sole plates
and oors, between wall-ceiling joints, between wall
panels, at penetrations for plumbing, electrical and gas
lines and other openings.
The following formula can be used to determine the maximum heater rating per the denition of unconned space:
BTU/Hr = (L1 + L2) Ft x (W) Ft x (H) Ft
50
Consider two connecting rooms with an open area
between, with the following dimensions:
L1 = 151/2 Ft., L2 = 12 Ft., W = 12 Ft., H = 8 Ft.
BTU/Hr = (151/2 + 12) x (12) x (8)
50
If there were a door between the two rooms the calculation
would be based only on the room with the heater.
BTU/Hr = (151/2) x (12) x (8)
50
W
H
Counter
Fireplace
Figure 2.3
If the area in which the heater may be
operated does not meet the required volume
for indoor combustion air, combustion and
ventilation air shall be provided by one
of the methods described in the National
Fuel Gas Code, ANSI Z223.1/NFPA 54, the
International Fuel Gas Code or applicable
local codes.

The chimney ue and rebox must be cleaned of
soot, creosote, ashes and loose paint by a qualied
chimney cleaner.
WARNING
This log set can be installed in a solid fuel burning
fireplace (masonry fireplace or manufactured
replace) with a working ue and constructed of
non combustible material or in a vent-free rebox.

Assembly Procedure
1. Attach the two brackets shipped with the engine
assembly to the engine base on the right and left hand
side using the two sheet metal screws shipped with the
brackets.
2. Center the burner assembly inside the fireplace or
firebox. Make certain that the front of the burner
assembly sits inside the front edge of the replace or
the rebox.
3. Anchor holes are located on the right and left sides of the
brackets attached to the engine base. After centering
the burner assembly correctly, mark the holes on the
replace or rebox oor. Drill two (2) 5/32” diameter holes
approximately 1 ¼” deep. Anchor the two anchoring
screws shipped with the unit using ¼” hex head chuck
and secure the burner assembly to the replace through
the holes drilled earlier.
You must secure the gas log heater to the replace
oor. If not, the entire unit may move when you
adjust the controls. Movement of unit may cause
shifting of the gas logs which leads to sooting and
improper burning. Grate movement could cause a
gas leak.
Special care is required if you are installing the unit
into a sunken replace. You must raise the replace
oor to allow access to gas log controls. This will
insure adequate air ow and guard against sooting.
Raise the fireplace floor using noncombustible
materials, as described in Placement in a Fireplace
with Restrictive Barrier on Page 7.

Gas Information
A. Gas Line Connection
NOTICE: A qualied gas appliance installer must connect
the heater to the gas supply. Consult all local codes.
IMPORTANT: Hold heater valve rmly with a wrench to
prevent movement when connecting to inlet pipe.
Always use an external regulator for all propane/LPG
heaters and high pressure one to two-pound systems
only, to reduce the supply tank pressure to a maximum of
13" w.c. This is in addition to the internal regulator in the
heater valve.
The heater gas inlet connection is a 3/8" NPT at the valve.
On all control type units, the inlet connection is on the right
side of unit. To connect from the opposite side, route the
pipe around the back portion of the unit.
When tightening up the joint to the valve, hold the valve
securely to prevent movement.
Test all gas joints from the gas meter to the heater valve for
leaks using a gas analyzer or soap and water solution after
completing connection. DO NOT USE AN OPEN FLAME.
Check the gas pressure with the appliance burning and
the control set to HIGH.
B. Millivolt Valve Control
The valve regulator controls the burner pressure which
should be checked at the pressure test point.
Turn captured screw counter clockwise two or three turns
and then place tubing to pressure gauge over test point
(Use test point “OUT” closest to control knob). After taking
pressure reading, be sure and turn captured screw clock-
wise rmly to re-seal. Do not over torque. Check for gas
leaks.
Use new black iron or steel pipe. Internally tinned
copper or copper tubing can be used per National
Fuel Code, section 2.6.3, providing gas meets
hydrogen sulde limits, and where permitted by local
codes. Gas piping system must be sized to provide
minimum inlet pressure (Listed on Data Plate) at the
maximum ow rate (BTU/hr). Undue pressure loss
will occur if the pipe is too small.
A manual shutoff valve must be installed upstream
of the appliance. Union tee and plugged 1/8" NPT
pressure tapping point should be installed upstream
of the appliance.
WARNING
Connecting directly to an unregulated propane/
LPG tank can cause an explosion.
WARNING
CHECK GAS TYPE: The gas supply must be the
same as stated on the heater’s rating plate. If the
gas supply is different, DO NOT INSTALL THE
HEATER. Contact your dealer for the correct model.
