Installation
Incorrect installation or unheeded warnings could result in
a serious fire, and loss of life and property.
Product is
NOT
designed for installation in “zero-clearance” fireboxes
or mobile homes, or in conjunction with gas log sets.
Inspect the chimney flue and fireplace for loose mortar, damaged
brick, and creosote build-up. Contact a professional chimney sweep or
building contractor for more information or repair.
After assembly, place unit into fireplace opening, making sure to cen-
ter unit in the opening. Use feet adjustment bolts to level unit.
Route the blower cord to desired location. Plug in the cord and check
for proper blower operation. See “Blower” section in Operating In-
structions for explanation of switches.
Unit will not run until the thermal switch reaches 120° F. If you wish
to test the unit when finishing installation, heat the thermal switch
(
silver disk on back of Blower Assembly
) with a lighter or torch after
setting the variable speed switch on.
Operating Instructions
Fuel:
WARNING:
Never use gasoline or any flammable liquid to start a fire!
Dry, seasoned hardwood is the safest and most efficient firewood. Rec-
ommended firewood age is 6-9 months.
When wood is green and/or burned very slowly, it produces tar and
other organic vapors, which combine with expelled moisture to form
creosote. This creosote residue accumulates on the flue lining, and
when ignited, can start an extremely hot chimney fire. The chimney
should be inspected for creosote build-up twice monthly during the
heating season, and cleaned as necessary.
Make certain to keep wood well back from the door opening in order to
avoid puncturing or placing extreme heat on the glass.
Regulate the fire in order to avoid the dangers and unnecessary wear
associated with extreme heat and uncontrolled burning.
Ashes should be placed in a metal container with a tight fitting lid and
retained there until all cinders have thoroughly cooled. Remember
that bottom, sides, and handles of container may be very hot.
Blower:
Blower is operated by a thermostatically controlled variable speed
switch. This means the blower will not turn on until temperatures
reach 110
°
-120
°F. Additionally, the unit will automatically turn
off when tem-
peratures drop below 90
°
F. To turn on, turn switch clockwise until
desired fan speed is achieved. To turn off, turn switch counter-
clockwise until a positive “click” is heard.
In event of power failure, open doors fully to minimize heat buildup.
WARNING:
Disconnect power source prior to performing any mainte-
nance or diagnostic operation on the blower or switches!
Assembly
Incorrect assembly or unheeded warnings could result in a
damaged unit, or a serious fire and loss of life and property.
Refer to included photo addendum to aid in assembly.
Step 1.
Unpack Heat Grate and identify all parts using Parts List and
place Heat Grate Unit on a flat surface to prepare for assembly. Be
sure to orient the unit with the manifold facing you.
(Fig. 1)
Step 2.
The power cord can exit the unit on the left or right side. De-
termine which side is the best power source. The Heat Transfer Bar
and Blower Assembly need to be installed on the side you choose.
Step 3.
Attach the Heat Transfer Bar
(“L” shaped metal bracket)
to
front of Log Holder with small bolt and nut.
(Fig. 2)
Step 4.
Remove cover from Blower Assembly. Place Blower Assembly
on desired side of Heat Grate by tipping the Heat Grate up and sliding
the manifold down between the Blower Assembly box and heat shield.
Make sure the Heat Transfer Bar slides between the Blower Assembly
box and heat shield, and rests on the thermal switch (
silver button
).
Step 5.
Align holes and bolt the Blower Assembly to the Heat Grate
unit using supplied Philips head screws.
(Fig. 3)
Step 6.
Route Cord out of the Blower Assembly on the proper side. Be
sure to place rubber grommet in case opening.
(Fig. 4)
Step 7.
Connect Cord wires to Blower and Switch wires by joining ter-
minals. Connect Green Wires to each other. Connect White from
Power Cord to Black from Fan. Connect Black from Power Cord to
Black from Switch.
See wiring diagram for more info.
(Fig. 5)
Step 8.
Place Blower Vent Assembly on opposite side of Heat Grate
from the Blower Assembly. Bolt to Heat Grate in same manner as
Blower Assembly in Step 4.
(Fig. 6)
Step 9.
Assemble Cover by sliding the two cover pieces together. Place
Variable Speed Switch through hole in cover. Trim ends of Cover to fit
into the fireplace opening. Place caps on each end of the Cover, mak-
ing sure to use Cap with cord cutout on the side where the Cord exits
the unit.
(Fig. 7)
Step 10.
Slide assembled unit into fireplace. Use feet adjustment
bolts on bottom of feet to level unit in fireplace.
(Fig. 8)
Step 11.
Install doors on top of cover and plug Grate Heater power
cord into 110v electrical outlet.
