New York City Approval - Superior SSDVST-CNM Installation Instructions Manual

These fi replaces are designed as supplemen-
tal heaters. Therefore, it is advisable to have
an alternate heat source when installed in a
dwelling.
Millivolt Models - The millivolt appliances are
manually controlled and feature a spark igniter
(piezo) that allows the appliance's pilot gas to
be lit without the use of matches or batteries.
This system provides continued service in the
event of a power outage.
Millivolt models come standard with a manu-
ally-modulated gas valve; fl ame appearance and
heat output can be controlled at the gas valve.
The BTU Input for these appliances is shown
in Table 1.

Test gauge connections are provided on the
front of the millivolt gas control valve, identi-
37,500 high
fi ed IN for the inlet and OUT for the manifold
30,000 low
side. A 1/8" NPT Test gauge connection
is provided at the inlet and outlet side of
the electronic gas control valve.
These appliances must be isolated from the
gas supply piping system (by closing their
individual manual shut-off valve) during any
pressure testing of the gas supply piping
system at test pressures equal to or less
than 1/2 psig (3.5 kPa).

These appliances and their individual shut-

greater than 1/2 psig (3.5 kPa).
Orifi ce Sizes - Sea Level to High Altitude
(All Models)
These appliances are tested and approved for
installation at elevations of 0-4500 feet (0-1372
meters) above sea level using the standard burner
orifice sizes (marked with an "*" in Table 6). For
elevations above 4500 feet, contact your gas
