Be sure to watch your EQUALS! Use disclaimers in Spec!

WATCH HORIZONTAL EQUIV.

MULTIPLE BOILERS AND HOW THEY ARE BREECHED.

CAN BE VERY NOISY.. WHERE IS MECH ROOM LOCATED

VARIES BY MANUFACTURER WATCH YOUR SPECS AND EQUALS!

THROUGH A BRICK WALL IS RISKY BUSINESS!

( NOT ALL CONDENSING BOILER REQUIRE ALL OF THESE

CONSIDERATIONS )

LOOK FOR PD AND GPM REQUIREMENTS.

LOW FLOW MEANS HIGH DELTA T. WATCH RISE AT HIGHER TEMPERATURES.

PRIMARY SECONDARY MAY BE NEEDED.

( NOT ALL CONDENSING BOILER REQUIRE ALL OF THESE

CONSIDERATIONS )

GAS REQUIREMENTS CAN BE AS HIGH AS 8” WC. TOUGH IN MANY AREAS OF CLEVELAND AND AKRON.

USE SPECIAL CARE WHEN USING MULTIPLE BOILERS.

ABILITY TO FIRE ALL BOILERS AT VARIOUS CAPABLE FIRING RATES MEANS ‘CAREFUL’ SIZING OF MAIN GAS BRANCH AND GAS DROPS TO BOILER.

( NOT ALL CONDENSING BOILER REQUIRE ALL OF THESE

CONSIDERATIONS )

NEGATIVE CONDITIONS CAUSE RANDOM HARD TO DETECT LOCKOUTS.

DIRECT CONNECT – BE SURE TO SPEC FACTORY FREEZE PROTECTION.

SIDEWALL – BE SURE TO USE SAME SIDEWALL AS VENT.

INLET AIR PIPE CAN CONDENSE AND DRIP IF NOT INSULATED OR DOUBLE WALL

DON’T COMBINE AIR INLETS

( NOT ALL CONDENSING BOILER REQUIRE ALL OF THESE

CONSIDERATIONS )

KNOW THE SYSTEM TEMPERATURE LIMITATIONS

CONDITION OF THE SYSTEM AND WATER (SMALL PASSAGES)

CONVERTING VENT? LINING CHIMNEY? SIDE WALL PLUME AND BRICK DAMAGE?

MULTIPLE BOILERS DON’T ALWAYS NEED HIGH TURNDOWNS.

WILL BACK LOADING MAKE SENSE?

DON’T LOOK AT LITERATURE FOR OUTPUT – CHECK CHART
