WARNING: Improper installation, adjustment, alteration, service or maintenance can
cause property damage, injury, or death. Read the installation instructions thoroughly
before installing this equipment.

Description/
Application

IMPORTANT

NOTE: These

are not gas
conversion

kits, ignition

conversion only.

NOTE: A unit with a
vent damper (Option
AV7) requires P/N
257010, an ignition
controller for
intermittent spark
pilot with lockout

The ignition conversion kits in this form are for Model F and Model B unit heaters equipped
with standing pilot and single stage gas valve. Before beginning conversion, determine
that your kit is compatible with your heater. Spark-ignited, intermittent safety pilot systems
without lockout are not available with propane gas; propane gas requires 100% lockout.

WARNING: This ignition conversion kit is to be installed by a qualied agency in

accordance with these instructions and in compliance with all codes and requirements
of authorities having jurisdiction. Failure to follow instructions could result in death,

serious injury, and or property damage. The qualied agency performing this work

assumes responsibility for this installation.

Instructions for
Installing Ignition
Conversion Kit

1. Turn off the gas supply at a shutoff valve upstream of the combination valve and turn

off the electrical supply.

2. Change Combination Valve
Disconnect the main gas line, the wires and the pilot tubing from the valve and remove the

valve. Install the valve provided with the kit being sure that the gas ow through the valve

is in the proper direction and that the valve is in an allowable orientation. Follow the valve
manufacturer’s instructions and, if applicable, the replacement valve kit instructions for
details on installing the valve.
Reconnect the main gas line. Do not reconnect the pilot tubing or wires at this time.

WARNING: The operating valve is the primary safety shutoff.
The gas supply line must be free of dirt or scale before connect­ing the unit to ensure positive closure.

3. Install the Ignition Controller (See FIGURE 1 for location.)

Attach the ignition controller mounting bracket to the rear of the heater using the holes in
the cabinet and the #10x3/8” screws in the kit. Position the ignition controller on the bracket
with the wire terminals across the bottom. Use the #8x5/8” screws to attach the ignition
controller to the bracket.

4. Change Pilot

Remove the two screws located at the rear bottom of the
heater that retain the bottom access panel. Allow the bot­tom panel to hinge down from the front.

The bottom of the pilot is now visible (See FIGURE 4A,
below.) Remove the screws holding the match-lit pilot
and remove the pilot assembly.

The match-lit pilot consisted of the pilot with hood and the ame-sensing thermocouple.
The new spark pilot assembly has a hooded pilot, a ame sensor rod, and an ignitor. Before

installing the pilot, verify the correct spark gap between the pilot hood and the ignitor. See
FIGURE 3. The spark gap must be maintained at .100”. The spark gap is set by the manu­facturer and should be correct, but it is wise to recheck before installation. If adjustment is
required, hold the ceramic base with a pair of pliers while adjusting the rod.

Install the spark pilot assembly being sure that the pilot burner is extended toward the
burner tube. Be sure to include the pilot shield that is used only with the spark pilot assem­bly. (See FIGURES 4A, 4B, and 4C.)

The controller
has a safety
feature that
once it is used
with a vent
damper, it
will no longer
operate a unit
without a vent
damper.

Attach one end of the ame sensor wire (150°C red silicone wire) to the ame probe on
the pilot assembly. Attach the other end of the ame sensor wire to Terminal “SENSE” on

the ignition controller. Attach the free end of the high tension spark wire (wire attached to

the ignitor on the pilot assembly) to the spike (“SPARK”) terminal on the ignition controller.
Push the wire rmly so that the spike is fully inserted and the wire secure.

Connect the pilot tubing to the gas valve. Position the tubing, high tension wire and ame

sensor wire in a location where they will not interfere with gas or air entering the burner or

be pinched by the bottom panel. Do not wrap the high tension wire and the ame sensor

wire together. The tubing and the wires may be routed through the opening for the manifold
pipe.

5. Wiring (Follow the appropriate new wiring diagram label in the kit.)

Remove the outer left heater side panel (left when facing the rear of the heater), revealing
the wiring.

Using the wires on the heater and the new wire assemblies in the kit, make the connec­tions according to the instructions below and the new wiring diagram label in the kit.

(a) Replace transformer – Models with standard 115 volt supply require a transformer

change when converting to spark ignition. Models with optional 208, 230 or 460 sup­ply voltage do not require a transformer change. If your unit requires a transformer
change, disconnect the wires from the transformer and remove the transformer from
the heater. (See FIGURE 1.) To install the new transformer, through the “large” hole in
the side panel for mounting the transformer, slide the Tinnerman clips over the trans­former screw holes. Insert the new transformer in the mounting hole and fasten with
the 1-3/4” long screws included in the kit. Reconnect the brown wire from the terminal
strip and the line voltage yellow and black wires. Do not reconnect the blue wire.

(b) ECO (Energy Cutoff) Wiring – The ECO wiring on a unit with a standard pilot is

routed through the rear of the heater. When the unit is converted to spark, the ECO
wiring must be re-routed through the side panel. Follow these instructions to re-route
and reconnect the ECO wires (Refer to Wiring Diagram on page 6):

(1) On the rear of the heater (fan panel), remove the Heyco device (strain relief bush-

ing) that holds the two red wires going through the fan panel. (These wires were
disconnected from the gas valve in Step 2.)

(2) On the side of the heater, remove the small fan/limit control access panel (See

FIGURE 5). Reach through the access hole and pull both red wires completely

through the fan panel into the heater where the ECO is located. One of these
wires will be used on the converted heater, but the other must be replaced with
the longer red wire in the conversion kit. Carefully disconnect one of the wires
from the ECO control and discard that wire. The red ECO wire in the kit has two
different terminals. Connect the end with the straight insulated terminal to the
ECO control.

(3) Remove the Heyco device (See FIGURE 5) from the inner side panel. Add the two

red ECO wires to the fan and limit wires that are already there. Using pliers, rein-

stall the Heyco device. Check to be sure that none of the wires (ECO, fan or limit)
come in contact with the heat exchanger tubes.

(4) Connect the red ECO wire with the 90° insulated terminal to the transformer. If

a new transformer was not installed, disconnect the blue wire to make this con­nection. If a new transformer was installed, make the connection on the 24V side
where the blue wire had been connected to the old transformer.

(5) At the terminal strip (See FIGURE 1), disconnect and discard the blue wire. At the

same place on the terminal strip, connect the other red ECO wire.

(6) Re-attach the small fan and limit control access panel.

(c) Combination Gas Valve – Connect the blue, black, and brown wires from the igni-

tion control. Attach the blue wire either to the P, TH-TR or PV terminal, depending on
the gas valve model. Attach the black wire to either M, TH or MV terminal. Attach the
brown wire to the terminal marked either C, TR or PV-MV (See Diagram, page 6).

6. Change the Lighting Instruction Plate and the Wiring Diagram on Heater

Lighting Instruction Plate – The new lighting instruction plate is self-adhesive and can be

placed over the original lighting instruction plate. Make sure the surface of the old instruc­tion plate is clean and dry. Remove the backing and adhere the new lighting instruction
plate so that it covers the original standing pilot instruction plate.

Wiring Diagram – The new wiring diagram is also self-adhesive and is made to cover the
original diagram on the heater.

If the heater is a Model F; a Model B with a direct drive blower motor; a Model B with a belt­driven blower with a motor without a contactor; or a Model B with a belt driven blower with
a motor with a contactor, select the diagram that matches the heater. Remove the backing
and adhere it over the diagram on the heater.

If the heater is a Model B with a belt-driven blower with a motor with a starter, contact your
Reznor Representative, providing the complete model number, the serial number, and the
number of the wiring diagram originally supplied on the heater. When the custom wiring
diagram arrives, verify that it matches, remove the backing, and adhere it over the wiring
diagram on the heater.

FIGURE 7 - Proper
Flame Adjustment

7. Check the main gas line for leaks using a commercial leak detecting uid or a rich

soap and water solution. Leaks are indicated by the presence of bubbles.

WARNING: All components of gas supply must be leak tested
prior to placing equipment in service. NEVER TEST FOR LEAKS
WITH AN OPEN FLAME. Failure to comply could result in severe
personal injury, property damage or death.

Turn on the electric and the gas. Relight, following the instructions on the new lighting
instruction plate.

WARNING: In the event of improper ignition, wait at least ve

minutes before attempting to relight heater.

Check all gas connections including the pilot connections for leaks, If a leak cannot be
stopped by tightening, replace the part.

Observe the pilot ame through the pilot lighting hole. The ame should extend ½ to 1” past
the ame sensing device (FIGURE 7).

To adjust the pilot ame, remove the pilot adjustment cover screw from the combination

valve. Turn the inner adjustment screw clockwise to decrease or counterclockwise to
increase the pilot ame. Replace the cover screw after adjustment to prevent gas leak­age.

8. Adjust Manifold Pressure

Depending on how the unit was originally equipped, the correct pressure adjustment may
depend on the area of the country in terms of elevation. Check the elevation listed on the
rating plate.

If the rating plate indicates 0-2000 ft, and the installation is located at 0-2000 ft, follow

a)

the instructions to check the manifold pressure to be sure that it is 3.5 inches w.c. for
natural gas or 10.0 inches w.c. for propane.

If the rating plate indicates a higher elevation the elevation adjustment was made at the

b)

factory by an orice change. Follow the instructions to check the manifold pressure to be

sure that it is 3.5 inches w.c. for natural gas or 10.0 inches w.c. for propane.
If the rating place indicates 0-2000 ft and the actual elevation is higher, determine the

c)

correct manifold pressure for the elevation and follow the instructions to set the valve
outlet pressure.

Instructions:

With the manual valve positioned to prevent ow to the main burners, connect a

1)
manometer to the 1/8” pipe outlet pressure tap in the valve. Use a water column
manometer that is readable to the nearest tenth of an inch. NOTE: A manometer (uid-

lled gauge) is recommended rather than a spring type gauge due to the difculty of

maintaining calibration of a spring type gauge.
Remove the cap from the pressure adjusting screw and adjust the manifold pressure

2)
to the pressure determined to be correct for the installation. Cycle the main burners
once or twice to properly seat the adjustment spring in the valve.

WARNING: Manifold gas pressure must never exceed 3.5” w.c.
for natural gas or 10” w.c. for propane gas.

Measure the manifold pressure. If further adjustment is necessary, correct pressure setting

3)
by turning the regulator screw IN (clockwise) to increase pressure. Turn regulator screw
OUT (counterclockwise) to decrease pressure. When the pressure is correct, remove the

manometer and replace the cap. Check for leaks at the pressure tap tting.

CAUTION: DO NOT bottom out the gas valve regulator adjust­ment screw. This can result in unregulated manifold pressure

causing excess overre and heat exchanger failure.

With the heater operating, determine that the inlet pressure to the heater is between 5 and

3)
14 inches w.c. for natural gas or between 11 and 14 inches w.c. for propane gas. Take this
reading as close as possible to the heater. (Most heaters are equipped with gas valves

that have an inlet pressure tap.) If the inlet pressure is not within the specied range the

inlet pressure must be corrected and the manifold pressure re-checked.

If the gas valve has been adjusted for operation above 2000 ft, nd the high altitude

4)

manifold pressure label in the kit. Using a permanent marker, ll-in the pressure setting

and adhere the label to the heater in a conspicuous location close to the gas valve.

9. Check for reliable and safe operation by operating the heater for several complete
cycles. CHECK FOR PROPER OPERATION OF ALL SAFETY FEATURES.

WARNING: Wait at least ve minutes before attempting to relight

heater in the event of pilot outage or improper ignition.

10. Replace the side panel and close the bottom access panel. Restore the heater to

normal operation. If a thermostat with a heat anticipator is used, it should be reset to
approximately .8 amperes.
