Siebring ROYAL HEAT 240, Instructions Manual

Page: 9 / 29

PLACEMENT:
This unit is designed to be used in various configurations. In greenhouses it
may be positioned directly on the ground or suspended from the greenhouse
structure. In aircraft hangars or garages, the unit will need to be suspended.
1. This unit may be suspended if necessary. Suitable framework, capable of handling
the weight of the furnace, can be fabricated from angle, channel or tubing material.
An eye bolt can be inserted in each corner or end of the angles, channels or beams to
provide 4 corner support (4 req.). These bolts can then be installed thru a suitable
ceiling joist etc.
2. Obviously, the structure must be strong enough to carry the additional weight of the
furnace, snow load and any possible future modifications or additions.
240 RH – 650#, 360 RH – 780#.
2. In greenhouses, this unit is normally installed on four (4) bricks setting directly on the
ground. A variety of openings can be supplied on these furnaces.
3. The furnaces require:
A. 12” distance to any combustible material. (See General Info for exceptions)
B. 12” of space for combustion air and blower supply air.
C. Approximately 1 sq. ft. of inlet area per 150,000 BTU/hr input. In many cases,
normal building cracks make up more than this area.
D. Approximately 5 sq. ft. of return air area. The heated air must have a free path
out of and back to the furnace. DO NOT restrict the discharge vents.
E. A barometric device (supplied by the manufacturer) in the same room as the
furnace. On the RH360 model, a 12” extension must be installed between the
barometric device and the furnace to prevent back draft and to prevent flue gases
from entering the blower inlet.
F. Plenty of access space for servicing the blower motor, burner, etc. Access must
also be provided to reach the gas valve and shut offs in case of an emergency.
G. That all local codes are followed when installing the regulation flue pipes.
