the units.
• Place the unit on a level and non-combustible surface.
• Minimum clearances from combustibles:
- outlet, minimum 10 feet

• Manufacturer recommends a free zone of 5 feet around the unit and a minimum distance of 10
feet at the unit’s flue gas openings are to be maintained.
• If the unit is placed indoors, secure an adequate fresh air opening for the burner combustion air.
• The unit may not be installed and operated in premises where explosive or combustible fumes
or dust are present. Always check the regulation of local authorities.
• Be certain that neither the air inlet nor the air outlet is obstructed.
FUEL SUPPLY
• This heater is shipped as either natural gas or vapor propane. Check for proper pilot orifice in
burner (Midco burner only).
Natural Gas .052
Vapor Propane .046
• Be certain to use adequate hose or pipe size to ensure proper volume and pressure.
See Chart Below.
For supply pressures greater than 1/2psi
