Installation / Operation Instruction Manual

16
Pre-installation continued-
a) Boiler DOE heating capacity is 100,000 BTU per
hour or less, or
b) When boiler output required to satisfy domestic hot
water demand is at least 50% of the boiler output
required to satisfy space heating demand, or
c) When an interruption in space heating can be
tolerated during a long domestic hot water draw.
2. Non-Priority – Boiler output is divided between space
heating and domestic hot water heating. Delivery of
domestic hot water can be reduced during simultaneous
space and domestic hot water heating operations,
depending on such factors as boiler output, boiler over-
sizing, number of space heating zones calling for heat,
and the ratio of domestic hot water load to space
heating load.

CAUTION
This water heater must be located in an area where
leakage of the tank, water line connections, or the
temperature and pressure relief valve will not result in
damage to the area adjacent to the water heater or to
lower floors of the structure. When such locations cannot
be avoided, a suitable drain pan must be installed under
the water heater. The drain pan depth must be suitable for
draining and collecting water. The drain pan can be
purchased from your plumbing professional. The drain pan
must be piped to an adequate drain. The piping must be at
least 3/4 inch in diameter and pitched for proper drainage.
