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.

14.0) VENTING
Failure to do so may result in death, serious injury, property damage or illness
from Carbon Monoxide poisoning.
Heaters installed in an unvented mode require a minimum ventilation flow of
4 CFM per 1,000 Btu/hr of total installed capacity.
In buildings with airborne contamination the heater must be installed with
fresh air for combustion.

1. When venting the heater to o tside of b ilding thro gh a roof, se single-wall metal pipe. This is to be
constr cted of galvanized sheet metal or other approved noncomb stible corrosion-resistant material as
allowed by state or local codes.
2. A vent passing thro gh a comb stible roof shall extend thro gh an approved clearance roof thimble. Do ble-
wall, Type B vent m st be sed for the portion of the vent system which passes thro gh the comb stible roof.
An approved vent cap m st be attached to end of the fl e.
3. The maxim m eq ivalent length of vent pipe sho ld be caref lly observed. A safety switch in the heater is
designed to sh t the heater off before excessive fl e restriction ca ses bad comb stion. Refer to the Vent
Sizing Table for maxim m vent lengths and vent pipe diameter.
•Minim m Eq ivalent Length = 5 ft. of pipe
•Maxim m Eq ivalent Length = 75 ft. of pipe
Use the following correction factors to obtain the eq ivalent length:
•S btract 15 ft. if the r n is horizontal.
•S btract 10 ft. for an approved vent cap.
•S btract 10 ft. for each elbow beyond 15 ft. from the heater.
•S btract 15 ft. for each elbow within 15 ft. of the heater.
4. Joints between sections of piping shall be fastened by sheet metal screws or other approved means and
sho ld be sealed to prevent leakage of fl e gas into b ilding. For Residential Installations:

5. Avoid locating elbows in the first 5’ of vent pipe whenever possible. Limit to (2) 90° elbows. When vent pipe
is in a horizontal r n, it m st have 1/4 inch per foot rise.
6. All portions of the vent pipe shall be s pported to prevent from sagging (6’ spacing is recommended).
7. When the vent pipe passes thro gh areas where the ambient temperat re is likely to ind ce condensation
of the fl e gases, the vent pipe sho ld be ins lated and a condensation drain sho ld be provided.
8. Minim m clearance for single-wall fl e pipe to comb stible material shall be 6 inches. This may be red ced
when the comb stible material is protected as specified in the National F el Gas Code or the a thority
