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. Val-Co 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 on all sides for burner servicing
and removal.
• To provide the owner with a copy of this
Installation, Operation and Service Manual.
• To never use heater as a support for a ladder or
other access equipment and never hang or
suspend anything from heater.
• To ensure there is adequate air circulation around
the heater and to supply air for combustion,
ventilation and distribution in accordance with
local codes.
• To safely and adequately install heater using
materials with a minimal working load of 75 lbs
(33 kg).
• To ensure the heater is placed in an approved
application.
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 Val-Co or your VAL-CO
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 VAL-CO 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 6, Figure 3 through Page
7, Figure 8. Write the proper clearance dimensions in
permanent ink according to your model number and
configuration in the open spaces on the tag.
2.2 Corrosive Chemicals
Val-Co 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.
CAUTION
Product Damage Hazard
Do not use heater in area containing
corrosive chemicals.
Refer to appropriate Material Safety Data
Sheets (MSDS).
Failure to follow these instructions can result
in product damage.

SECTION 3: CLEARANCES TO COMBUSTIBLES
5 of 53
SECTION 3: CLEARANCES TO COMBUSTIBLES
3.1 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 that 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 6, Figure 3 through
Page 7, Figure 8 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.
• The stated clearances to combustibles represents
a surface temperature of 90 °F (32 °C) above
room temperature. Building materials with a low
heat tolerance (such as plastics, vinyl siding,
canvas, tri-ply, etc) may be subject to degradation
at lower temperatures. It is the installer’s
responsibility to assure that adjacent materials
are protected from degradation.
• Maintain clearances from heat sensitive
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, building construction, 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 on Page 15, Figure 11.
• 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.
WARNING
Fire Hazard
Keep all flammable objects, liquids and
vapors the minimum required clearances to
combustibles away from heater.
Some objects will catch fire or explode when
placed close to heater.
Failure to follow these instructions can result
in death, injury or property damage.
