11. INSTALLATION
A. Properly size and install ventilation as per Section 8, gas supply as outlined in Section 9,
previous page, and electrical supply as per Section 10 above.
B. Ensure adequate clearance around air openings into the combustion chamber
C. The ignition control assembly is shipped in the carton with the heater. Assemble the gas
valve / ignition control assembly to the heater at the gas-supply union.
D. Suspended infrared heaters shall be fixed in position independent of gas and electric supply
lines. Hangers and brackets shall be of non-combustible material. Heaters subject to vibra-
tion shall be provided with vibration-isolating hangers.
E. Suspension hardware must be of adequate capacity to support the weight of the heater -
see Table 4 next page. Typical suspension chain is #8 Jack Chain (60 lb work load rating)
and/or #2 Lion Chain (also called “Double Loop” Chain) (115 lb work load rating).
F. For Seismic & Wind condition suspension see Figure 7 page 18
G. Mounting at an angle of up to 30°: see Figure 6 page 18
 Rotate on the short axis only - long axis must always be horizontal
 The venturi side of the heater must be in the upper position when angle mounted
 The ‘center of gravity’ of the heater allows angle mounting up to 30° using the sus-
pension tabs attached to the heater
E. Mounting at an angle greater than 30° up to 45°: see Figure 6 page 18
 Rotate on the short axis only - long axis must always be horizontal
 The gas-supply/venturi side of heater must be in the upper position when angle
mounted
 The heater requires an Angle Mounting Bracket (JO-0331-XX - available as an op-
tional accessory) for angle mounting over 30° up to 45° - the Angle Mounting
Bracket bolts to the suspension tabs on the heater - see Figure 6 page 18
F. Mount heaters to structure by using non-combustible mounting hardware such as that illus-
trated in FIGURE 5 on page 18.
G. Observe the minimum clearances to combustibles as per the Clearance To Combustibles
section and Figure 1 and Table 1 pages 6, 7.
H. In locations used for the storage of combustible materials, signs shall be posted to specify
the maximum permissible stacking height to maintain required clearances from the heater
to the combustible materials. SEE PAGE 8
I. Connect heater to the main gas line. It is recommended to use a 1/2" flexible connector
(available as option from Schwank) to absorb gas line expansion and any vibration from the
building. The flexible gas connector must be formed into a smooth ‘C’ shape.
J. Mount thermostat at desired location, away from direct infra-red rays of heater. If the ther-
mostat is located on a cold wall, place sufficient insulation behind the thermostat.
K. Test gas line for leaks by using gas pressure test and/or soap test and as per all local and
national codes. Ensure gas pressure meets the requirements outlined in Section 9.
When testing the main gas line pressure, ensure the gas shut-off valve is “OFF”, oth-
erwise damage to the combination gas valve can result.
L. Test fire the heating system by following the lighting instructions on the next page and on
heater.
