Your LONGVIE heater is especially designed to provide maximum comfort to you and your home. Its large solid injected aluminum front grill assures the optimum use of the generated heat in the ambient, maintains normal temperatures behind the heater to avoid sticking of particles, which would soil the wall. You can feel safe with absolute security guaranteed by:

Its thermocouple security valve, which cuts the supply of gas in the event of the heater extinguishing due to strong air

• currents, momentary interruption of the supply of gas.

Its gas pressure regulator assures an optimum operational; function, avoiding peak pressures in the gas supply

• affecting normal combustion.

Its gas tight combustion chamber, totally enameled, avoids gases which are caused by combustion, to contaminate

• the air and ensures a useful , long lasting working life.

Long lasting working life...Guaranteed by the quality of its components and high technology applied in the process of fabrication, and especially by the traditional vocation of LONGVIE to produce durable products for your maximum comfort and satisfaction.

Input ratings are shown in BTU per hour and are for elevations up to 2,000 feet. For elevations above 2,000 feet, input

14.

ratings should be reduced 4 percent for each 1,000 feet above see level. Refer to the National Fuel Gas Code. The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during any

15.

pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa). The appliance must be isolated from the gas supply piping system be closing its equipment shutoff valve during any

16.

pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa). This gas appliance must not be connected to a chimney flue serving a separate solid-fuel burning appliance.

17.

The installation make provisions for adequate combustion and ventilation air.

18.

The installation must provide adequate accessibility clearances for servicing.

VENTILATION INSTALLATION

The ventilation system consist of:

1_External Tube - Air incoming tube with enamel hood riveted in place. 1_Threaded Mounting Rod 1_Internal Tube - Outgoing flue gases 1_Adjusting Nut

For Model DV12:

Mark the three 5/16” (8mm) holes and drill Insert the three plastic plugs provided in the previously drilled

holes. Mark the hole for the 4-1/2” (11.5cm) dia. ventilation tube.

This must be rectilinear and with a slight fall towards the exterior of approx. 2 degrees to avoid the entering of rain water.

Take into consideration the area indicated for the gas connection.

The wall’s thickness cannot be less than 4-1/2” (11.5 cm) nor can it exceed 13-1/2” (35cm). (See Diagram Nº 5) Tube lengths and threaded mounting rod should be trimmed to comply to the dimensions shown in Diagram Nº 3.

For Model DV20:

Mark the four(4) 5/16” (8mm) holes and drill Insert the four(4) plastic plugs provided in the previously drilled

holes. Mark the hole for the 6 1/4” (16cm) dia. ventilation tube. This

must be rectilinear and with a slight fall towards the exterior of approx. 2 degrees to avoid the entering of rain water.

Take into consideration the area indicated for the gas connection.

Final Assembly

Remove the front cover of the heater by removing the control knob and the two(2) screws on the top of the cover. Slide the front upwards.

After tubes have been cut to length, slide the tubes and the rod into position on the heater and adjust with the nut provided until you get a compact unit.

Slide the heater and ventilation assembly through the hole until the heater reaches the wall. For the model DV12, se- cure to the wall with the three(3) screws provided. For the model DV 20, secure to the wall with the four(4) screws provided.

Check that hood protrudes the intended 4 1/4” (10.8 cm) from the exterior wall. Seal any imperfections between wall and vent hood with putty, making sure that nothing falls inside the hood. (See

Diagram Nº 6) A protection plate resistant to high temperatures is available at extra cost for use with external combustible walls. (See

Diagram Nº 7)
