Installation & Operation Manual
Sizing
The SYNC boiler uses model specific combustion air intake and vent piping sizes as detailed in Table 2A below.
When determining equivalent combustion air and vent length, add 5 feet for each 90° elbow and 3 feet for each 45° elbow.
EXAMPLE: 20 feet of PVC pipe + (4) 90° elbows + (2) 45° elbows + (1) concentric vent kit (CVK3003) = 49 equivalent feet of piping.
