WARNING
It is the responsibility of the installing contractor to see that all controls are correctly installed and are
operating properly when the installation is complete.
DO NOT operate the water heater with jumped out or absent controls or safety devices.
DO NOT tamper with or alter the water heater and/ or controls.
DO NOT operate the water heater if any external part has been under water. Immediately call a qualified
service technician to inspect the appliance and to replace any part of the control system that was under
water.
DO NOT install this water heater on carpeting. This water heater is suitable for installation on combustible
flooring.
DO NOT operate this water heater witho ut first being certain it is filled with water.
Flammable items, pressurized containers, or any other potential fire hazardous articles must never be
placed on or adjacent to the heater. Containers of flammable gases should not be stored o r used in the
same room with this water heater. Hydro gen gas can be produced in an operating water heater that has
not had water drawn from the tank for a long period of time (generally two weeks or more). Hydroge n gas
is extremely flammable. To prevent the possibility of injury under these conditions, we recommend that
the water faucet be opened for several minutes at the kitchen sink before you use any electrical applian ce
that is connected to the hot water syste m. If hydrogen is prese nt, there will be unusual sounds such a s air
escaping through the pipes as hot water begins to flow. Do not smoke or have open flame near the faucet
at the time it is open.
CAUTION
The maximum boiler water supply temp erature to the indirect heat exchanger must not exceed 200°F
(93°C).
NOTICE
Insulation blankets are not requi red for this water heater. This water heater meet s or exceeds the
ASHRAE/IES 90.1b standards with resp ect to insulation and standby loss requi rements.
NOTICE
The maximum heat transfer through the coil (h eat input) of the water heater at 200°F (93°C) boiler wate r
supply temperature and 210°F potable water tempe rature is 94,000 Btu/hr. Potable water temperature is
limited to below 210°F and nominal water containing capacity is less tha n 120 gallons for all indirect
models. Accordingly, per Part HLW-101.2, Section IV of the ASME Boiler and Pressure Vessel Code, all
indirect products are therefore exem pted from compliance with the code.
