TOA Electronics SSDV-3328 SSDVT/R-3328, Electronic Models, 17,500, Gas Pressure All Models

These appliances are designed to operate on natural or propane gas only. To operate on Propane Gas a field converion is necessary (see Pages 34 to 36). Do not use any other fuels. The use of other fuels, or combination of fuels, will degrade the performance of this system and may be dangerous.

These fireplaces 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; flame 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- fied IN for the inlet and OUT for the manifold 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-off valves must be disconnected from the gas supply piping system during any pressure testing of that system at pressures greater than 1/2 psig (3.5 kPa).

Orifice 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 supplier or qualified service technician . Install the appliance according to the regulations of the local authorities having jurisdiction and, in the USA, the National Fuel Gas Code NFPA 54 / ANSI Z223.1 - latest edition or, in Canada, the CAN1-B149.1 and .2 codes - latest edition.
