INSTALLATION REQUIREMENTS
The installation m st conform to local b ilding codes or in the absence of local codes, with the National F el Gas
Code ANSI Z223.1/NFPA54 or the Nat ral Gas and Propane Installation Code CSA B149.1. Heaters shall be
installed by a licensed contractor or licensed installer. Clearances to comb stibles as o tlined in this man al
sho ld always be observed. In areas sed for storage of comb stible materials where they may be stacked
below the heater, NFPA54 req ires that the installer m st post signs that will “specify the maxim m permissible
stacking height to maintain the req ired clearances from the heater to comb stibles.”
Every heater shall be located with respect to b ilding constr ction and other eq ipment so as to permit access
to the heater. Each installer shall se q ality installation practices when locating the heater and m st give
consideration to clearances to comb stible materials, vehicles parked below, lights, overhead doors, storage
areas with stacked materials, sprinkler heads, gas and electrical lines and any other possible obstr ctions or
hazards. Consideration also m st be given to service accessibility.
The heater, when installed in aircraft hangars and p blic garages, m st be installed in accordance with
ANSI/NFPA 409-latest edition (Standard for Aircraft Hangars), ANSI/NFPA 88a-latest edition (Standard for
Parking Str ct res), and ANSI/NFPA 88b-latest edition (Standard for Repair Garages) with the following
clearances:

a.
Installation of this appliance is to be in accordance with latest edition of
CSA
B149.1 (
Nat ral Gas and
Propane Installation Code).
b. For installation in p blic garages or aircraft hangars, the minim m clearances from the bottom of the
infrared heater to the pper s rface of the highest aircraft or vehicle shall be 50 percent greater than the
certified minim m clearance, b t the clearance shall not be less than 8 feet.

Appliances are s pplied as standard for altit des of O to 2,000 feet (0-610 m). High-altit de ratings are obtained
by a change in the orifice size. When ordered for high altit de installations, b rners are s pplied by the factory
ready for high altit de installation. Check the nameplate for altit de before proceeding with the installation. In
Canada the adj stment for altit de is made in accordance with Standard CGA 2.17, Gas-Fired Appliances for Use

9.0) TYPICAL SUSPENSION METHODS
Burner must be secured to the mounting flange with nuts.
All materials used to suspend the heater must have a minimum working load
of 115 lbs.
All S Hooks must be crimped closed.
Never use the heater to support a ladder or other access equipment.
Failure to do so may result in death, serious injury or property damage.
SUSPENSION HAZARD
Vario s means of s spending the heater can be sed. See the following drawings for typical examples.
1. Use only noncomb stible materials for s spending hangers and brackets.
2. A minim m No. 2 chain with a working load limit of 115 lbs. is req ired.
3. T rnb ckles can be sed with chains to allow leveling of the heater. All “S” hooks and eye bolts m st be
man ally crimped closed by the installer.
4. When sing rigid means for heater s spension (rod, flat bar, etc.) provide s fficient lengths or swing joints to
compensate for expansion. See Fig res b and c.
5. Heaters s bject to vibration m st be provided with vibration isolating hangers.
6. Heaters m st not be s pported by gas or electric s pply lines and m st be s spended from a permanent
str ct re with adeq ate load capacity.
Space-Ray recommends that the t be sections be s spended sing chains with t rnb ckles. This will allow
slight adj stments after assembly and heater expansion/ contraction d ring operation.
If a “trapeze” method is sed for t be s pport/hanger brackets (shown below), the minim m chain length for the
two connecting chains is 36” to minimize any vibration that might be generated by the draft ind cer assembly. If
these chains m st be less than 36”, then do not se the trapeze method and, instead, se individ al chains on
each t be s pport/hanger bracket.

11.0) GAS CONNECTIONS AND REGULATIONS
Tighten flexible gas hose and components securely.
Flexible metal gas hoses must be installed without any twists or

and it can crack if it is twisted.
Failure to do so may result in death, serious injury or property
damage.

1. Connect to the s pply tank or manifold in accordance with the latest edition of National F el Gas Code (ANSI
Z223.1), and local b ilding codes. A thorities having j risdiction sho ld be cons lted before the installation
is made. (In Canada, refer to the latest edition of CSA Standard B149.1, Nat ral Gas and Propane
Installation Code.)
2. Check that the gas f el on the b rner rating plate matches the f el for the application.
3. Check that the gas s pply piping has the capacity for the total gas cons mption of the heaters and any other
eq ipment connected to the line.
4. Check that the calc lated s pply press re with all gas appliances and heaters operating will not drop below
the minim m s pply press re req ired for these heaters. Check inlet s pply press res on Section 12.0).
5. All gas s pply lines m st be located in accordance with the req ired clearances to comb stibles from the
heater as listed on the clearances label of the heater and Section 4.0) of this man al.
6. Pipe joint compo nds m st be resistant to the action of liq efied petrole m gases.
7. T be heaters will expand/contract d ring operation. Where local codes do not prohibit, a CSA or U.L.
approved flexible connector s pplied with this heater is req ired for connections between the rigid piping
