GENERAL INFO:

This unit complies with the American National Standard for Gas Unit Heaters
(special units, which are not AGA certified, may also use this manual).

1. The installation must conform with all local codes, or, in the absence of
local codes, it must follow the National Fuel Gas Code, ANSI Z223.1-1988.

2. All installation and servicing must be handled by qualified personnel.

3. This furnace should not be operated in an explosive or dusty environment.

4. This unit can be set up to run on Natural Gas or Liquid Propane (LP) gas.
The orifices must be sized appropriately for each gas type and pressure.

5. The draft hood provided with each furnace must be installed vertically in
the same air space as the furnace. This unit must be vented.

6. If this unit is used to heat an adjacent area, (not the same airspace as the
furnace is in) an adequate air return area must be provided.

7. In greenhouses, this unit may be positioned on four (4) concrete block or
bricks.

8. In garages, this unit should be suspended with at least 7’ of clearance
under the furnace. In garages, install this unit in accordance with the
Standard for Repair Garages ANSI / NFFA 88B and follow all local codes
that apply.

9. In aircraft hangars, this unit should be suspended with at least 10’ of
clearance from the wings or engine cowling, based on the highest aircraft
normally stored in the hangar. Install this furnace in accordance with the
Standard for Aircraft Hangars ANSI / NFPA 409.

10. Do not locate this unit closer than 12” to any combustible material, this
includes the chimney, all four sides and top of the unit. The furnace may
be set on any suitable non-combustible material.

11. Do not locate any items within 12” of the burner opening. This includes the
combustion air supply and the blower inlets. Floor drafts can cause pilot
outages.

12. If installed in parking structures, the Standard for Parking Structures ANSI /
NFPA 88A should be followed.

The chimney height will be determined by the
surrounding roof & trees. The chimney should
extend at least 24” above the high point of the
roof with no obstructions from nearby roofs,
trees or other structures.

Gas fired units will require less draft than coal
fired, however, a chimney flue with adequate
draft and capacity is required. An A.G.A. draft
diverter must be installed on all gas-fired
heating units.

General Information & Instructions

-Unit crated weights: 240 = 640 lbs. / 360 = 780 lbs.

-Always use double wall pipe on gas units.

-Never have less than .02 - .04 inches of draft in the chimney.

-Always use black metal piping for gas (Nat./L.P.) installations.

-Rule of thumb for chimneys = 2’ vertical for every 1’ horizontal.

-Always check with the gas company on appropriate pipe sizing.

-Always check with the gas company to ensure adequate fuel supply.

-Never reduce the size of chimney from the furnace to the draft cap.

-Never run exhaust fans in any building while furnaces are in operation.

-Always vent gas fumes. Gas fumes not vented can cause death to plants, animals and humans.

-The draft diverter must always be installed VERTICALLY unless otherwise stated by Siebring Mfg.
Warranty will be void if venting does not meet local codes for gas venting.

Electrical Information

Important!

Before beginning any electrical work, be
certain the electrical supply is disconnected.
For the furnace to operate properly, it must
be wired exactly as outlined in this manual.

Connect to 120 VAC 60 HZ 25A Service

An electrical diagram has been provided in this manual and on the face of the furnace.

1. If any wires as originally supplied are replaced, they should be replaced with type “T”
wires, with a 63°F (35°C) rise wire in similar colors.

2. Follow all local codes when wiring this furnace.

3. This furnace must be electrically grounded in accordance with the National Electrical
Code, ANSI / NFPA 70.

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.
