ANGLE MOUNTING
This heater is suitable for mounting angles with the short
axis rotated in either direction as shown in Figure 3.
Improper angle mounting can result in damage to the
heater or unsafe operation.
IMPORTANT:
For either horizontal or angle mounting,
the long axis of the heater must be level. Use only non-
combustible mounting hardware. In general, mounting
angles above 25° are only used for special application of
spot and area heating.

VENTILATION REQUIREMENTS
Natural or mechanical means shall be provided to
exhaust at least 4 CFM per 1,000 BTU per hour
input on installed heaters on Natural gas, 4.5
CFM per 1,000 BTU per hour input on installed
heaters on LP gas. Exhaust openings for remov
ing flue products shall be above the level of the
heaters.
When buildings are so tight that normal
infiltration does not provide the necessary air for
combustion, outside air must be introduced.
IMPORTANT:
PIPING PRACTICES
1. Installation of ground pipe joint union is
required at the gas inlet connection to the
control valve on the heater. All components
upstream of the control valve are field sup
plied by the installer. See Figure 4.
2. If permitted by code, an approved 18” or 24”
flexible connection between the heater and
piping is recommended.
3. Installation of a 6” gas line trap “Drip-Leg” is
required at the inlet connection to the
heater. Failure to provide a drip leg could
result in condensation and foreign matter in
the valve which could cause damage.
4. On propane-fired heaters, a main line filter
is recommended.
5. Installation of a manual shut off valve is
required. Provide a 1/8 inch N.P.T. plugged
tap, accessible for test gauge connection,
immediately upstream of the gas supply
connection to the heater. It may be part of
the shut off valve as shown in Figure 4.
6. Piping joint compounds must be resistant to
the action of liquefied petroleum gases.
7. All piping must be installed according to
local codes.
8. To insure proper performance and full input
capacity, the gas supply line leading to the
heater from the main supply should be of an
adequate size. Check your local plumbing
codes for correct sizing for your installation.
