IMPORTANT:
IF GRILLS ARE USED ON THE OUTSIDE WALL, THEY MUST BE SIZED PROPERLY.
MOST SIDEWALL GRILLS HAVE ONLY 50% FREE AREA. IN THE CASE OF A UNIT WITH
100,000 BTU/HR INPUT, WHICH REQUIRES A PAIR OF 8” (203mm) ROUND PIPES TO
OBTAIN SUFFICIENT COMBUSTION AND VENTILATION AIR, THE DUCT COULD BE AN
EQUIVALENT RECTANGULAR DUCT; 8” X 7” (203mm X 178mm) FOR EXAMPLE. BASED
ON 50% FREE AREA FOR THE INLET GRILLS, THE ACTUAL GRILL SIZE WOULD HAVE
TO BE 14” X 8” (356mm X 203mm) OR ITS EQUIVALENT. A TRANSITION MAY BE USED TO
REDUCE TO THE SMALLER DUCT SIZE IF NECESSARY.
IMPORTANT:
THE OUTDOOR GRILLS MUST BE INSTALLED IN A LOCATION WHERE THEY WILL NOT BE
OBSTRUCTED IN ANY MANNER.
