WARNINGS
Selection of replacement control parts from this manual and all servicing to Reznor® products must
be done by a Reznor® Distributor or other qualied technician. Improper selection or servicing
could result in severe personal injury, death, or property damage. Reznor Corporation will accept
no responsibility or liability as a result of improper servicing of Reznor® products.

SAFETY WARNINGS AND GUIDELINES FOR A QUALIFIED SERVICE TECHNICIAN
When selecting a replacement control, always have the complete Model No. and Serial No. of the heater.
(See pages 2-4 for instructions on decoding those numbers.) If the model and serial number are not
available, contact your Reznor® Representative. DO NOT SELECT REPLACEMENT CONTROLS WITH-
OUT COMPLETE INFORMATION.
Before servicing a heater, always turn off the gas and the power supply. Because of the electrical safety
features, never turn off the power supply without turning off the gas.
The electrical operating valve is the primary safety shutoff. The gas supply line must be free of dirt or
scale before connecting the valve.
Leak test all gas connections including pilot connections. Test using a commercial leak detecting or a
soap solution. WARNING: DO NOT TEST WITH OPEN FLAME. If a leak cannot be stopped by tightening,
replace the part.
In the event of pilot outage or improper ignition, wait at least ve minutes before attempting to relight
the heater.
After any service is completed, always test for proper operation. Re-connect the electrical supply and
turn on the gas. Verify against operating sequence information on the heater and in the heater installation manual. Safety check the installation and equipment. CHECK THAT ALL SAFETY DEVICES ARE
FUNCTIONING PROPERLY.

FOR YOUR SAFETY
WARNINGS
The use and storage of gasoline or other ammable vapors and liquids in the
vicinity of this heating appliance is hazardous.
DANGER
The gas burner in all Reznor® gas-red equipment is designed and equipped to provide safe, complete
combustion. However if the installation does not permit the burner to receive the proper supply of
combustion air, complete combustion may not occur. The result is incomplete combustion which
produces carbon monoxide, a poisonous gas that can cause death. Safe operation of indirect-red
gas burning equipment requires a properly operating vent system which vents all the products to
the outside atmosphere. Failure to provide proper venting will result in a health hazard which could
cause serious personal injury or death.
Always comply with the combustion air requirements in the installation codes and instructions.
Combustion air at the burner should be regulated only by manufacturer-provided equipment.
NEVER RESTRICT OR OTHERWISE ALTER THE SUPPLY OF COMBUSTION AIR TO ANY HEATER.
Indoor units installed in a conned space must be supplied with air for combustion as required
by code and in the installation manual. ON INDIRECT-FIRED EQUIPMENT, MAINTAIN THE VENT
SYSTEM IN PROPERLY FUNCTIONING CONDITION. Direct-red and other unvented installations
should provide for air changes as required by applicable installation codes.
Instructions
for Selecting a
Replacement
Ignition Controller
and/or Valve
Serial No. Codes - Identify the code of the valve or ignition controller needing replacement.
Serial No. Codes are dened on pages 3-5. IMPORTANT NOTE: Serial No. and Model No.
Codes apply only to original equipment.
IGNITION CONTROLLER - To select the replacement ignition controller, locate the Serial No.
safety pilot code in the listing on pages 6-10. Select carefully, reading all applicable notes. If the
part is no longer available from Reznor, a functional replacement or alternative instructions are
listed.
VALVE - To select a replacement valve, locate the Serial No. valve code in the listing on pages
12-19. The valve supplied on the heater is described. If the valve is no longer available from
Reznor, a functional replacement or alternative instructions may be listed. Select carefully, read-
ing all applicable notes. All valve code notes are on pages 20-22. See pages 23-27 for representative illustrations of valves.

When the current inventory of this valve is depleted, a SINGLE mechanical modu-
lation replacement valve WILL NO LONGER BE AVAILABLE.
WARNING: Do not replace an existing mechanical modulation valve with mechanical modulation valve Code R7, R8,
R9, or S1 ONLY. To do so will result in an unsafe condition.
Replacement requires dual functional valves. A mechanical modulation valve plus
either a solenoid valve or a single-stage valve depending on the application are
required.
Field-furnished pipe nipples will be required to adapt the manifold for the two
replacement valves. Install valves in series with single-stage or solenoid valve rst
and mechanical modulation valve second in the gas stream.
The chart below lists dual functional replacement valves by model/size/gas type
combinations. Valves are available for most sizes. When functional replacement
valves are not available from Reznor, contact valve manufacturer concerning availability of a functional replacement.

NOTE 44: When installing this valve as a replacement for a valve with a different
Serial No. Valve Code on a Model PDH, SDH, RDH, SHH, or RHH, a new valve
bracket is required.
• For PDH, SDH, and RDH Sizes 75, 100, 125, and 150, order bracket P/N
261650.
• For PDH, SDH, and RDH Sizes 175 and 200, order bracket P/N 261249
• For SHH and RHH Size 130, order bracket P/N 261650.
• For SHH and RHH Size 180, order bracket P/N 261249.

NOTE 45: As a result of continued product improvement, the valve that is factory
installed on these Model RDCB/RDDB heat section sizes was changed from slow
opening to standard opening effective 8/09. When replacing, the valve listed here is
the appropriate functional replacement.
Replacement Valves (cont'd) - Identied by Third Element of the Serial No. (see pages 11-22).
