SECTION 1: HEATER SAFETY
Your Safety is Important to Us!
This symbol is used throughout
the manual to notify you of
possible fire, electrical or burn
hazards. Please pay special
attention when reading and
following the warnings in these
sections.
Installation, service and annual inspection of heater
must be done by a contractor qualified in the
installation and service of gas-fired heating
equipment.
Read this manual carefully before installation,
operation or service of this equipment.
Due to the nature of gas conversions, it is important
you use the correct conversion kit for the heater
model and gas you are converting to. Use only
genuine ROBERTS GORDON® conversion kits.
This heater is designed for heating nonresidential
indoor spaces. Do not install in residential spaces.
These instructions, the layout drawing, local codes
and ordinances, and applicable standards that apply
to gas piping, electrical wiring, venting, etc., must be
thoroughly understood before proceeding with the
installation.
Thin sheet metal parts, such as the reflector portion
of the heater and the various venting components,
have sharp edges. To prevent injury, the use of work
gloves is recommended. The use of gloves will also
prevent the transfer of body oils from the hands to the
surface of the reflector.
WARNING
Explosion Hazard
Turn off gas supply to heater before service or
maintenance.
Failure to follow these instructions can result in
death, injury or property damage.
WARNING
Electrical Shock Hazard
Disconnect electrical power before service or
maintenance.
Failure to follow these instructions can result in
death or electrical shock.
Before installation, check that local distribution
conditions, nature of gas and pressure, and
adjustment of the appliance are compatible.

VANTAGE® NP FUEL CONVERSION INSTRUCTIONS
SECTION 2: INSTALLER RESPONSIBILITY
The installer is responsible for the following:
• To install the heater, as well as the gas and
electrical supplies, in accordance with applicable
specifications and codes. Roberts-Gordon
recommends the installer contact a local Building
Inspector or Fire Marshal for guidance.
• To use the information given in a layout drawing
and in the manual together with the cited codes
and regulations to perform the installation.
• To install the heater in accordance with the
clearances to combustibles.
• To furnish all needed materials not furnished as
standard equipment.
• To plan location of supports.
• To provide access to burners for servicing on all
sides, for burner removal.
• To provide the owner with a copy of this
installation, operation and service manual.
• To never use heater as support for ladder or other
access equipment and never hang or suspend
anything from heater.
• To safely and adequately install heater using
materials with a minimal working load of 75 lbs.
(33 kg).
• To ensure there is adequate air circulation around
the heater and to supply air for combustion,
ventilation and distribution in accordance with
local codes.
2.1 Wall Tag
A laminated wall tag is available for the heater as a
permanent reminder of the safety instructions and the
importance of the required clearances to
combustibles. Please contact Roberts-Gordon or your
ROBERTS GORDON® independent distributor to
obtain the wall tag. Affix the tag by peeling off the
backing of the adhesive strips on the rear surface and
position the tag on a wall near the heater (e.g.
thermostat or ROBERTS GORDON® Controller).
A copy of the wall tag (P/N 91037912) is illustrated on
the back cover. For an immediate solution, you may
affix this copy on the wall near the heater.
Know your model number and installed configuration.
Model number and installed configuration are found
on the burner and in the Installation, Operation and
Service Manual. See Page 13, Figure 11 through
Page 14, Figure 16. Write the proper clearance
dimensions in permanent ink according to your
2
model number and configuration in the open spaces
on the tag.
2.2 Corrosive Chemicals
CAUTION
Do not use heater in an area containing corrosive
chemicals.
Avoid the use of corrosive chemicals to ensure a
longer life of the burner, tubing and other parts.
Failure to follow these instructions can result in
property damage.
Roberts-Gordon cannot be responsible for ensuring
that all appropriate safety measures are undertaken
prior to installation; this is entirely the responsibility of
the installer. It is essential that the contractor, the
sub-contractor, or the owner identifies the presence
of combustible materials, corrosive chemicals or
halogenated hydrocarbons* anywhere in the
premises.
* Halogenated Hydrocarbons are a family of chemical
compounds characterized by the presence of halogen elements
(fluorine, chlorine, bromine, etc.). These compounds are
frequently used in refrigerants, cleaning agents, solvents, etc. If
these compounds enter the air supply of the burner, the life span
of the heater components will be greatly reduced. An outside air
supply must be provided to the burners whenever the presence
of these compounds is suspected. Warranty will be invalid if the
heater is exposed to halogenated hydrocarbons.
2.3 National Standards and Applicable Codes
All Appliances must be installed in accordance with
the latest revision of the applicable standards and
national codes. This refers also to the electric, gas
and venting installation. Note: Additional standards
for installations in Public Garages, Aircraft Hangars,
etc. may be applicable.
In Canada, the conversion shall be carried out in
accordance with the requirements of the provincial
authorities having jurisdiction and in accordance with
the requirements of the CAN-B149.1 and CAN/CGA
B149.1 and B149.2 Installation Codes for Gas
Burning Appliances.

VANTAGE® NP FUEL CONVERSION INSTRUCTIONS
SECTION 6: CRITICAL CONSIDERATIONS
6.1 Required Clearances to Combustibles
Clearances are the required distances that
combustible objects must be away from the heater to
prevent serious fire hazards. Combustibles are
materials, which may catch on fire and include
common items such as wood, paper, rubber, fabric,
etc. Maintain clearances to combustibles at all
times for safety.
Clearances for all heater models are located on the
burner of the heater and on Page 13, Figure 11
through Page 14, Figure 16 in this manual. Check the
clearances on each burner for the model heater
being installed to make sure the product is suitable
for your application and the clearances are
maintained. Read and follow the safety guidelines
below:
• Keep gasoline or other combustible materials
including flammable objects, liquids, dust or
vapors away from this heater or any other
appliance.
• Maintain clearances from heat sensitive material,
equipment and workstations.
• Maintain clearances from vehicles parked below
the heater.
• Maintain clearances from swinging and overhead
doors, overhead cranes, vehicle lifts, partitions,
storage racks, hoists, etc.
• In locations used for the storage of combustible
materials, signs must be posted to specify the
maximum permissible stacking height to maintain
required clearances from the heater to the
combustibles. Signs must be posted adjacent to
• the heater thermostat. In the absence of a
• thermostat, signs must be posted in a
conspicuous location.
• Consult local Fire Marshal, Fire Insurance Carrier
or other authorities for approval of proposed
installation when there is a possibility of exposure
to combustible airborne materials or vapors.
• Hang heater in accordance to the minimum
suspension requirements in the heater’s
Installation, Operation and Service manual.
• If the radiant tubes must pass through the building
structure, be sure that adequate sleeving and fire
stop is installed to prevent scorching and/or fire
hazard.
12
WARNING
Fire Hazard
Some objects will catch fire or explode when placed
close to heater.
Keep all flammable objects, liquids and vapors the
required clearances to combustibles away from heater.
Failure to follow these instructions can result in death,
injury or property damage.
SECTION 6: CRITICAL CONSIDERATIONS
NOTE: 1. All dimensions are from the surfaces of all tubes, couplings and elbows.

SECTION 7: OPERATION AND MAINTENANCE
SECTION 7: OPERATION AND MAINTENANCE
7.3 To Start Heater
Turn gas valve and electric power OFF and wait five
minutes for unburned gases to vent from heater.
Turn ON main gas valve.
Turn ON electric power.
Set thermostat to desired temperature, burner should
light automatically.
7.4 Pre-Season Maintenance and Annual Inspection
To ensure your safety and years of trouble-free
operation of the heating system, service and annual
inspections must be done by a contractor qualified in
the installation and service of gas-fired heating
equipment.
The CTHN-Series series heater is equipped with a
direct spark ignition system.
7.1 Sequence of Operation
1. Turn the thermostat up. When the thermostat
calls for heat, the pump will start immediately.
After a small delay, the burners will begin their
ignition sequence, 45 seconds later, sparking
will begin at the electrode. Upon sparking of the
electrodes, the gas valve is energized.
2. The flame will be sensed by the flame sensing
rod and the electrode is de-energized.
3. If a flame is detected, the gas valve remains
open. When the call for heat is satisfied, the
burner shuts off. On CTHN-Series systems
equipped with the optional ROBERTS
GORDON® controllers, the pump will continue
operation for a post-purge period of two
minutes.
Disconnect gas and electric supplies before
performing service or maintenance. Allow heater to
cool before servicing.
Before every heating season, a contractor qualified in
the installation and service of gas-fired heating
equipment must perform a thorough safety
inspection of the heater.
For best performance, the gas, electrical, thermostat
connections, tubing, venting, suspensions and
overall heater condition are some of the areas
requiring inspection.
NOTE: Gas flow and burner ignition are among the
first things that should be inspected.
Please see Page 18, Section 7.5 for suggested items
to inspect.
4. If no flame is detected, the gas valve is closed
on the module and a purge period begins. After
the purge, the module sparks, and there is a
second trial for ignition. If flame is still not
established, a third purge, and trial cycle begins.
After 3 trials, the module will lockout until reset.
Reset is accomplished by removing power from
the module for at least 5 seconds (thermostat
cycle required).
7.2 To Shut Off Heater
Set thermostat to lowest setting.
Turn OFF electric power to heater.
Turn OFF manual gas valve in the heater supply line.
