Installation and Operating Instructions
- Installation and Operating Instructions -
Congratulations!
The Grate Heater can be used in a wood-burning masonry fireplace with any set of glass doors and features
a concealed blower that retains the natural beauty of
your fireplace. With proper care and maintenance, the
Grate Heater is a safe and efficient insert for your fireplace.
This unit is recommended for use with a glass door enclosure. Using the Grate Heater in conjunction with glass
doors produces maximum performance from the fireplace
and presents a lower operating fuel cost.
INSTALLATION INSTRUCTIONS:
All units com e with a front grill 1-3/8 inch high and 48
inches wide. This unit will force more heated air into the
room and allow a more comfortable temperature during
the brisk winter months by having one (1) venting outlet.
After installing, avoid building a raging fire in the fireplace. The fan wi ll d is tr ibu t e more heat direc tly to the
room if the burn cycle is even. Overfiring can cause
discoloration to any glass door unit and may damage
the heat exchanger.
Step 1.
Verify that the Grate Heater is the proper size for the
fireplace.
Step 2.
For fireplaces with existing glass doors, make sure
they can be elevated 1-3/8 inch. Remove the glass
doors. Insert the Grate Heater and reposition the glass
door on top of the riser bar. This will elevate the glass
door 1-3/8 inch.

Step 3.
Mount extender bars on the heat exchanger with the
metal screws provided (see Figure 1).
Step 4.
Place the glass door enc losur e on the f ront of the exchanger, making sure the glass door and heat exchanger
are centered in the fireplace.
Step 5.
Remove the extender bars and cut them so the total

riser bar width is the same as the glass enclosure. Cut
the cord shield to the desired length and slide it on the
extender bar where cord is introduced (this protects the
cord from heat). Place the end caps on the ends of the
extender bars with the notched cap on the cord side
(see Figure 1).

Reposition and secure the glass door according to the
glass door instruction manual.
Step 7.
For a dropped hearth installation, the back legs come
standard with 1/2 inch nuts and it is recommended that
1/2 inch x 2-1/2 inch bolts be used. (Not included).
Step 8.
Plug cord into nearest outlet. Exchanger will start when
temperature reaches 110
Note: Grate heater fan should be plugged in at all
times when the unit is inuse, otherwise damage to
the motor will occur.

OPERATING INSTRUCTIONS
1. On initial start-up of the Grate Heater, there will be
some smoke produced. This is a burn-off of oil used
in manufacturing of this unit. The smoke will subside after the first firing. The fan should be left on
low speed, with the fireplace doors open. The smoke
can be minimized by placing a damp cloth over the
heat outlet.
2. The blower sliding vent should only be open when
glass doors are not used or in the event of a power
failure or blackout. Under these conditions the vent
is used to cool the blower.
3. This unit is equipped with a three (3) wire ground
cord for protection. Never remove the ground lead.
Be sure the electrical plug provided is plugged into a
proper three (3) prong outlet. If an extension cord is
used, be sure it has the proper ground and is of the
same or greater value than the cord provided on the
Grate Heater. If the extension cord is too light the fan
may fluctuate its speed and operate improperly.
4. P
eriodic removal and cleaning of ashes on the square
tubing will increase heat output and maximize effi-

ciency.
5. Under normal use the blower on the Grate Heater
should be oiled every 4,000 hours of operation. There
is an opening on the top of the motor where the
lubricant can be applied (see Figure 2).

DESCRIPTION

Blower Motor

Rheostat SRV01-510
1. Blower will not turn on.
If a fire has not been started on the heat exchanger,
the fan will not come on. Because the Grate Heater
is thermostatically controlled, it will not turn on until
the thermostat, located on the top of the motor box,
reaches 110
take 15 to 30 minutes before the fan will turn on.
The blower will automatically turn off at a temperature of 90
2. Blower turns on and off while fire is burning.
Check the thermal sensor tab which is 1 inch wide
and 4 inches long, located on the top of the motor
box, extending over the thermostat (see Figure 1). It
conducts the heat from the Grate Heater to the sensor so the motor is activated. If the motor is starting
and stopping, you may need to tighten this tab so it
is touching the thermostat. This can be done with a
standard screwdriver. Tighten the tab only so it is
touching the thermostat. Do not overtighten.
3. Motor hums upon starting.
Be sure the Grate Heater is unplugged before
checking for potential problems.
R
emove the left side panel of the motor box by taking out the front screw of the motor box. (There is a
screw on the backside, but it is only a guide to hold
the panel in place). Push forward and the panel will
come free. After removing this panel check to see if
the motor is in place. Two (2) sheet metal screws
top and bottom hold the motor in the housing. If one
of the screws has come loose (from vibration) the
motor cannot turn freely. To correct this, reattach
the two (2) screws which will secure the motor and
allow it to turn freely.

4. Blower will not turn on after the fire has been
started.
If the motor does not turn on after starting a fire,
several items can be checked. Be sure the unit is
unplugged before checking for potential problems.
Check the thermal sensor as indicated in Step 2.
Check the motor and the wiring to the motor. The
motor must be free to turn and the wiring must be
intact and attached to both the therm os tat and the
rheostat. If you notice that any of the wires coming
from the motor are bare, it will be necessary to replace the motor. This can be done by removing the
two (2) screws that attach the motor to the housing.
he problem is in the thermostat, the thermostat
If t
must be replaced. T he thermostat is held in place
by two (2) rivets which can be drilled out from the top
with a 1/8 inch drill bit. When replacing the thermostat use either rivets or sheet metal screws to hold it
in place.
The rheostat, the speed control in the front of the
heater, may also need to be replaced if it is operating improperly. To remove the rheostat, take the
knob off and then loosen the screw on the front of
the heater. Using a pair of pliers, release the heyco
connector or stress relief (located on the right side
of the front, behind the extender) so the wiring to
the rheostat is free. Unplug the connectors and replace the rheostat.
With proper care and maintenance, your Grate Heater
should give you years of efficient heat circulation while
maintaining the natural beauty of your fireplace.
