Please leave these instructions with the appliance.
Please retain these instructions for future reference
.
1. The installation, combustion and ventilation air
must conform with local codes or, in the absence of
local codes, with the National Fuel Gas Code, ANSI
Z223.1.
2. Installation and repair should be done by a qualied
service person. Vermont Castings Group Vented Gas
Logs must be installed only in a masonry or a UL 127
solid-fuel replace with minimum venting requirements,
see installation section.
3. To prevent malfunction, gas log set and ue should
be cleaned at least annually by a professional service
person. More frequent cleaning may be required due
to excessive lint from carpeting, etc. It is imperative
that control compartments, burners and circulating air
passageways be kept clean.
5. Never burn solid fuels in a replace where a gas log
set is installed.
6.
A replace screen must be
in place when the log set is burning. Provisions for
adequate combustion air must be provided. Adequate
combustion air usually results in all ames curling into
the replace away from screen and up the ue.
8. Keep room area clear and free from combustible
materials, gasoline and other ammable vapors and
liquids.
9. Children and adults should be alerted to the hazard
of high surface temperature and should stay away to
avoid burns or clothing ignition.
10. Young children should be carefully supervised when
they are in the same room with the gas log set in opera-
tion.
11. Do not place clothing or other ammable material near
the replace when the gas logs are in use.
12. Do not use this gas log set if any part has been under-
water. Immediately call a qualied service technician
to inspect the gas logs and replace any part of the
control system and any gas control which has been
under water.
13. The gas log set
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 (3.5kPa).
14. Secure gas log set to replace.
15. This log set will burn off the paint on the front grate
bar.
16.
Installation of this vented gas log in the Commonwealth
of Massachusetts requires the damper be permanently
removed or welded in the full open position. In addition, a
naturally vented gas log may not be installed in a bedroom
or bathroom in the Commonwealth of Massachusetts. Flex
line installation must not exceed 36".

The following are guidelines for placing a VWF log set in a replace that has a restrictive barrier
along the bottom front opening of the replace. Some examples of barriers are glass/screen door
frames and sunken/recessed replaces.
No Restriction 13" Manual Control
13Z\x" Millivolt Control
0 to 1Z\x" 15"
Greater than 1Z\x" to 3" 15"
Greater than 3" Any barrier greater than three inches (3") placed in front of the
gas log set is not recommended by the manufacturer

Glass door frames with
adjustable louvers should
have the lovers
while the unit is in operation.
Height of restrictive barrier caused
by glass door frames, recessed
replaces, etc. from the base or
bottom surface of the unit. (See Table).
The log set should be placed against
or as near as possible to the rear wall
of the replace/rebox.
Depth of replace/rebox.
(Refer to Table).
Noncombustible 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.

A damper stop must be provided with the unit. The damper
stop must be installed as shown in Figure 3 to prevent full
closure of the replace damper blade and provide a mini-
mum ue opening, according to the table on Page 5.
Should the clamp not t, or provide the required permanent
opening from the table, have the damper cut to provide
a minimum permanent opening or install a permanent
stop.
Installa-
tion of this vented gas log in the Commonwealth of Mas-
sachusetts requires the damper be permanently removed
or welded in the full open position. In addition, a naturally
vented gas log may not be installed in a bedroom or bath-
room in the Commonwealth of Massachusetts.

• Turn off gas supply to replace or rebox.
• Clean replace oor and chimney before installing log
set. Seal any ash clean out doors to protect the
unit from down drafts.

The Millivolt (thermopile) is a self powered combination gas
control that does not require 110V AC to operate. Refer to
Figure 7 and installation instructions provided with optional
wall switch or remote control for wiring instructions. A maxi-
mum length of 15 feet of 18 awg two conductor wire is to
be used for wall switch. Switches must be suitable
for millivolt operation. The optional wall switch must be
mounted outside the rebox. The remote receiver location
must not exceed a temperature of 120° F.
The millivolt system and individual components may be
checked with a millivolt meter having a 0-1000mV range.
Conduct each check shown in chart below by connection
meter test leads to terminals as indicated.
a. If the reading is more than 100 millivolts and the
automatic valve still does not come on — replace
the control.
b. If the closed circuit reading (“A” reading) is less
than 100 millivolts, determine cause for low reading
— proceed as follows:
A Complete TH & TH/TP Min. 100 mV
System
B Thermopile TP & THTP Min. 325 mV
Output
a. 325 millivolts minimum. If the minimum millivolt read-
ing is not obtainable, readjust pilot for maximum mil-
livolt output. If millivolt reading is still below minimum
specied, replace thermopile.

The gas log set gas inlet connection is 3/8" NPT at the
regulator, inlet on the right side facing the gas log. If a left
side connection is required, the connecting pipe may be
led under the rear of the gas logs or behind the grate for
connection to the inlet.
Test all gas joints from the gas meter to the appliance
regulator for leaks using a gas analyzer or soap and water
solution after completing connection.
Check the gas pressure with the appliance burning.
Figure 9
The pressure regulator is preset and locked to discourage
tampering. If the pressure is not as specied, replace with
the correct part from the parts list in this manual.
Remove 1/8" NPT plug, located on side of regulator body.
Install tting and tubing to pressure gauge. After taking
pressure reading, re-install test plug. which should be
checked at the pressure test point. Check for gas leaks.
Figure 10
The valve regulator controls the burner pressure which
should be checked at the pressure test point. Turn captured
screw counter clockwise 2 or 3 turns and then place tubing
to pressure gauge over test point (Use test port labeled
“OUT”). After taking pressure reading, be sure and turn
captured screw clockwise rmly to re-seal. Do not over
torque. Check for gas leaks.

Fill the burner pan with vermiculite to the bottom of the rear
log and sloped to the front edge of the burner pan. Excess
vermiculite can spill forward or to the side of the burner
pan. Do not overll the propane model. Do not cover the
pilot (if SPK or MVVK is installed) with vermiculite or rock
wool (embers).
The Wildre ame appearance can vary due to differences
in draft and replace congurations and ember placement.
After installing rear (#1) and front logs (#2 and #3), cover
the entire top surface of the vermiculite in the burner pan
with the rock wool supplied with unit. Tear the rock wool
into pieces approximately 1/2" in size (roughly the size of a
nickel) and cover the burner evenly. Do no use more rock
wool than the amount supplied with the unit. To enhance
the appearance of the Wildre ame, it is recommended
to form a mound of rock wool in the center of the burner,
2" to 3" high, visible through the two front logs.
Sprinkle volcanic rock in front of front glowing embers
and to both sides.
