supports and is hanging level. (Check crosswise and
lengthwise.)
3. See Fig. 5 for typical indoor installation. In any
installation, consideration must be given to making
sure the heater is located away from the people
entering or exiting the greenhouse so they cannot
accidentally knock the heater or tamper with the
heater and its gas supply line. Additionally, the
heater must be located so that it does not block the
normal entryway or exit of the building. Observe and
obey minimum clearance distances to combustible
materials as stated in the specification section of this
owner’s manual and on the heater’s dataplate.
