that does not reduce the performance of any fire rated assembly.
Do not use this water heater for anything other than its intended
purpose (as described in this manual). Doing so could result in
property damage and WILL VOID product warranty.
High heat sources (sources generating heat 100
greater, such as stove pipes, space heaters, etc.) may damage
plastic components of the water heater as well as plastic vent
pipe materials. Such damages ARE NOT covered by warranty. It is
recommended to keep a minimum clearance of 8" from high heat
sources. Observe heat source manufacturer instructions, as well
as local, state, provincial, and national codes, laws, regulations
and ordinances when installing this water heater and related
