Troubleshooting guide

1.1 Health and Safety
A. Heater is intended for heating
non-residential indoor spaces and should
only be installed where flammable gases
or vapors are not generally present.
B. Heaters may be suspended either
horizontal or at an angle, or may be wall
mounted. See section A3 for clearance
dimensions.
C. The installation must conform with local
building codes or, in the absence of local
codes, with the National Fuel Gas Code,
ANSI Z223.1/NFPA 54 or the Natural
Gas and Propane Installation Code, CSA
B149.1.
D. The unit shall be electrically grounded
accordance with National Electric Code
ANSJJNFPA 70-1987.
E. The heater may be installed in aircraft
hangars installed in accordance with the
Standard for Aircraft Hangars, ANSI/
NFPA 409 and in automotive garages
when installed in accordance with the
Standard for Parking Structures, ANSI/
NFPA 88A, or the Standard for Repair
Garages, ANSI/NFPA 88B, or the
Canadian Natural Gas and Propane
Installation Code, CSA B149.1, and are
so marked.
Ensure that minimum clearances will be
maintained to vehicles parked below the
heater.
1.2 Packing and Shipping Information
See section 2 for assembly drawings. Material
list with part numbers and descriptions for each
part will accompany each shipment.
Heaters include: Options:
Burner/Control
Heat Exchanger
Radiant Tubes
Reflectors/Canopies
Brackets Ball Valve
Fan Vent Hoods
U-Bend Hanging Assembly
Flex Gas Connector* (Chain etc)
Tube Couplings
* Connector must comply with ANSI Z21.24/CSA 6.10.
Shipping packages for individual projects will be
boxed and crated as outlined in the specific bill
of lading.
1.3 Heater Suspension
Attachment to the heater support lugs should be
made by a ‘speed link’, D shackle or in the case
of drop rods, a closed formed hook. The
hanging attachments to overhead steelwork
etc. must be purpose made to good sound
engineering practice or of a proprietary type
fixing. They must be adequately fixed and
designed to carry the whole weight of the
heater. In the event of suitable roof steelwork
being unavailable, additional steelwork should
be fitted to enable vertical hangers to be used
for suspending the heaters.
These methods are illustrated in Figure 1. If
there are any doubts as to the strength or
suitability of roof steelwork to which heaters are
to be suspended, please refer to a Consultant,
Architect or owner of the building.
It is recommended that the heater is raised to its
final position once the assembly of the tube/
bracket/reflector has been completed. Longer
tube assemblies may be raised in more than
one sub-assembly with final tube connection
made in the air.
The suggested mounting heights for AmbiRad
heaters are given in table 1 below.
1.4 Wall Mounting
These radiant tube heaters can be wall mounted
using the appropriate bracket.
When using the wall mounting brackets the
heater must be inclined at an angle between 35°
and 55°.
