B Vent.

MINIMUM CLEARANCES

This water heater is approved for installation on combustible flooring in an alcove with minimum clearance from combustion construction as indicated in below Figure and Table.

In all installations the minimum combustible clearances from vent piping shall be 6” (15.2 cm). Vent piping passing through a combustible wall or ceiling must be a continuous run (no joints) and retain 6” (15.2 cm) clearance unless an approved reducing thimble is used.

A service clearance of 24” (61 cm) should be maintained from serviceable parts, such as Temperature- pressure relief valves, baffles, digital thermostats, cleanout openings or drain valves.

The units are approved for installation with side, rear and ceiling clearances as indicated below:
