p. For multiple boiler installations with horizontal wall terminals, maintain minimum 12 in. (300 mm) horizontal
distance between adjacent boiler vent terminals. Maintaining greater spacing is recommended to avoid
frost damage to building surfaces where vent terminations are placed.
q. For multiple boiler installations with vertical roof terminals, maintain minimum 12 in. (300 mm) horizontal
distance between adjacent boiler vent terminals.
