ELECTRICAL WIRING (MILLI-VOLT)

The milli-volt valve is a self-powered combination gas control THAT DOES NOT REQUIRE 110 VAC TO OPERATE.

CAUTION

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

CONNECTING OPTIONAL WALL SWITCH OR THERMOSTAT

1.Use 18 awg, two-wire cable, 15 feet maximum length.

2.At one end of the cable, connect both wires to the wall switch or thermostat. At the other end, connect one wire to TP/TH and one wire to TH, or connect the wall switch/thermostat to the two male (0.25") terminals on the left side of the unit. The color of the wires does not matter.

CHECKING SYSTEM OPERATION

The millivolt system and individual compo- nents may be checked with a millivolt meter having a 0-1000mv range. Conduct each check shown in chart by connecting meter test leads to terminals as indicated.

A.COMPLETE MILLIVOLT SYSTEM CHECK

("A" Reading - Thermostat contacts CLOSED - Control Knob “ON” - Main Burners should turn ON)

a.If the reading is more than 175 millivolts and the automatic valve still does not come on - replace the valve.

b.If the closed circuit reading ("A" reading) is less than 175 millivolts, determine cause for low reading - proceed as follows:

B.THERMOPILE OUTPUT READING CHECK

(“B” Reading - Thermostat contacts OPEN - Main burner OFF)

Check gas pressure to the unit. If gas pressure is within minimum and maximum on data plate, then replace pilot. 500 millivolts minimum. If the minimum millivolt reading is not obtainable, replace pilot.

DSSPVMB, DSSNVMB specifications

Monessen Hearth has established itself as a reliable name in the realm of home heating solutions, providing innovative products that are both functional and aesthetically pleasing. Among its impressive line-up are the DSSNVMB and DSSPVMB models, which are designed to offer homeowners effective and stylish heating options.

The DSSNVMB (Natural Vent) and DSSPVMB (Propane Vent) are part of Monessen's commitment to creating products that look good while delivering exceptional performance. Both models feature a sleek, modern design that allows them to seamlessly fit into various types of home decor. Their visual appeal, combined with practical utility, makes them a popular choice among homeowners.

One of the most significant features of these models is their efficient venting system. The DSSNVMB utilizes natural venting technology, which allows it to expel exhaust gases through an existing chimney, eliminating the need for external venting systems. This feature not only saves on installation costs but also enhances the overall energy efficiency of the unit. In contrast, the DSSPVMB is designed for propane use, boasting a direct venting system that draws air from outside while expelling gases, creating a closed system that maximizes efficiency and safety.

Both models come equipped with advanced burner technology, ensuring an even and controlled flame that optimizes heat output. This means that homeowners can enjoy consistent warmth without fluctuations in performance. The adjustable flame settings allow users to customize their heating experience to meet individual preferences, creating a tailored comfort level.

Moreover, the DSSNVMB and DSSPVMB are designed with user-friendliness in mind. The easy-to-use control systems allow for straightforward operation, making it simple for homeowners to manage their heating needs. Additionally, these models often come with options for remote control, providing convenience in adjusting the temperature from anywhere in the room.

Safety is a top priority in the design of Monessen's products. The DSSNVMB and DSSPVMB are equipped with built-in safety features, including automatic shut-off systems that activate if any irregularities are detected during operation. This reassurance of safety provides peace of mind for users.

In summary, the Monessen Hearth DSSNVMB and DSSPVMB models exemplify modern home heating solutions that combine efficiency, user-friendliness, and design. With their advanced technologies, stylish appearance, and robust safety features, these units are perfect for any homeowner looking to enhance their living space while enjoying the comfort of efficient heating.
