CONTROL PANEL CLEARANCES
• The control panel MUST have a minimum side
clearance of 6" from any obstructions/side walls. See
Fig. 12-1.
(To allow for access to light switch and control panel
removal.)
• The control panel MUST remain removable for
servicing (see CONTROL PANEL REMOVAL section).
Any adjacent countertops must not obstruct the panel
from being removed.
COMBUSTION AIR AND COOLING AIRFLOW
Proper airflow (front-to-back, Fig. 12-2) MUST be maintained
for the unit to perform as it was designed. If airflow is blocked,
overheating and poor combustion will result. Do not block the
1" front air inlet along the bottom of the control panel.

within 6 feet of the unit. If it is located within
the enclosure, it must be easily accessible.
Use a pipe joint compound resistant to
all gasses on all male fittings except flare
fittings.
