This heater is used in VENTED or UNVENTED mode. The term Unvented actually means Indirect Vented . While
the products of combustion are expelled into the building, national codes require ventilation in the building to
dilute these products of combustion. This ventilation must be provided by gravity or mechanical means.
Ventilation requirements are addressed further in these instructions.
Although these heaters may be used in many applications other than space heating (e.g., process heating),
Space-Ray will not recognize the warranty for any use other than space heating.
This heater is not an explosion proof heater. Where the possibility of exposure to volatile and low flash point
materials exists, it could result in property damage or death. This heater must not be installed in a spray booth
where the heater can operate during the spraying process. Consult your local fire marshal or insurance company.
When installing Defenders into a barn with stalls or partitions, we recommend
that at least half of every stall area be covered with a heater.
Straight Configuration Only: Since straight tube heaters are always hotter at the control end than at the flue
terminal end, always observe the minimum recommended mounting heights shown on the specification sheets
and in Section 5.0) of this manual. Use U-tube configuration instead of straight tubes for spot or area heating (e.g.,
where a single heater is utilized for space heating).
High Altitude:
Appliances are supplied as standard for altitudes of O to 2,000 feet (0-610 m). High-altitude ratings are obtained
by a change in the orifice size. When ordered for high altitude installations, burners are supplied by the factory
ready for high altitude installation. Check the nameplate for altitude before proceeding with the installation. In
Canada the adjustment for altitude is made in accordance with Standard CGA 2.17, Gas-Fired Appliances for Use
at High Altitudes.
