A INSTALLATION INSTRUCTIONS
1 Operating and adjusting the
output to the radiation system
The COSMOGAS heater can be installed in
any domestic or light commercial building
where the maximum BTU/H required is not
greater than 88,800 BTU/H.
The unit has a internal mixing valve (heating
side only) that can be adjusted to regulate
the supply water temperature delivered to
the heating system.
The heating system will not receive any water
unless the water temperature inside of the
heater is at a minimum of 140°F. The heater
built-in domestic hot water priority thermostat
will cease the power to the circulator until
the temperature is greater than 140°F.
2 Location
This space/water heater unit is not intended for
outdoor installation. Choose a location centralized
to the piping system along with consideration to
the vent pipe length. Additionally, you will need to
place the space/water heater so that the controls,
drain, inlet/outlet, and gas valve are easily
accessed. Also, care must be exercised when
choosing the location of this appliance, where
leakage from the safety relief valves, leakage from
related piping, or connections, will not result in
damage to the surrounding areas, or to the lower
floor of the building.
No valve is to be placed between the safety relief
valves and the heater. The discharge from the
temperature and pressure relief valve must be
conducted to a suitable place for disposal. No
reducing coupling or other restriction shall be
installed in the discharge line. The discharge line
should allow complete drainage of both valve and
line.
3 Installation
The installation must conform to local codes and
ordinances or, in the absence of local codes, the
National Fuel Gas Code ANSI Z 223.1/NFPA 54
- 1984. When installed the appliance must be
electrically grounded in accordance with the
National Electrical Code, ANSI/NFPA No.70 -
1987.
For Canada, the installation should conform to
CGA B149.1 INSTALLATION CODES and/or local
installation codes.
The gas supply piping system should be tested
before the heater is connected.
The heater, (complete with all its parts: external
jacket, intake and discharge flue pipes, etc.), must
be installed leaving a distance of at least 10 cm,
(4”), from sidewalls and ceiling.
Installation of the BTS combi directly on combustible
flooring such as carpeting shall be installed on a
metal or wood panel extending behind the full width
and depth of the appliance by at least 3”, (76.2
mm), in any direction or, if the appliance is installed
in an alcove or closet, the entire floor shall be
covered by the panel.
