8. Installation
1. Before proceeding with installation, verify feasibility of the heater location, such that the heater,
electrical cord or gas piping will not be accessible to livestock. Allow for convenient access and
serviceability of equipment.
NOTE: DO NOT attach any inlet and/or discharge ductwork other than approved accessories to the
heater. Excessive static pressure may cause this heater to overheat and/or cause excessive
amounts of combustion products to be discharged into the space.
2. Maintain a minimum clearance from combustibles of 12" from the top, bottom and sides of the
heater. Combustible material must be a minimum distance of 6' from the discharge air outlet of
the heater.
NOTE: If the heater is located in a high-traffic area, mount the heater so as not to create a human
bump hazard; however, the minimum clearance for the combustibles must be maintained.
3. To protect the heater from livestock, this heater must be installed a minimum of 24" from the ground
in poultry applications and minimum of 48" from the ground in hog confinement. Verify that the
bottom air intake is not restricted in any manner.
Installation of Recirculating Type (Indoor)
1. Locate the four (4) eye bolts and jam nuts supplied with the suspension kit. Thread one (1) jam nut
onto each eye bolt. Thread eye bolts with jam nuts into each top corner of the heater. Screw the
eye bolt down until it stops. Tighten the jam nut against the heater’s housing. This will prevent the
eye bolt from backing out during heater operation.
2. Attach the “S” hook and chain to each eye bolt previously installed on the heater.
3. Secure the mounting hardware to adequate support members so that the heater support chains are
located at an angle that minimizes swaying motion. Verify that the heater is securely fastened and
that it is hanging level. (Check with a level in both the lengthwise and crosswise directions.)
4. Install the gas piping and the electrical wiring in accordance with local codes, or, in the absence of
local codes, with the National Electrical Code and ANSI/NFPA 70-1993 and the standard for the
storage and handling of liquefied petroleum.
5. Install a manometer to the gas valve to verify that the gas pressure is within the range specified on
the heater’s nameplate.
6. Check all gas connections for leaks, using a leak detector solution. Repair any gas leak before test
firing or placing this heater into service.
7. Install a sediment trap and a manual shut off cock to the heater’s gas inlet.
Gas supply pressure exceeding 14" W.C. (1/2 PSI) can cause damage to the
automatic gas valve, the heater’s components and/or personal and property
damage due to fire or explosion.
