OPERATING OPTIONAL GWMT1

WALL MOUNTED THERMOSTAT

WARNING: Do not connect the thermostat to a power source. Electrical shock and/or a ﬁre hazard will occur.

Light the ﬁreplace as instructed in Lighting Instructions on page 23. Set wall thermostat to desired temperature.

This thermostat has been electronically calibrated at the factory and requires no adjustment or leveling.

Upon installation, the thermostat must be allowed to stabilize at room temperature for a minimum of 30 minutes for proper operation.

To turn the ﬁreplace off, adjust thermostat to the lowest set- ting and turn the gas control knob back to PILOT. The pilot will remain lit.

IMPORTANT: To turn the pilot off, turn the gas control knob on the heater to the OFF position.

OPERATING OPTIONAL

BLOWER ACCESSORY

Locate the blower controls by opening the lower louver panel on the ﬁreplace. Blower controls are located on the right side of the switch bracket to the left just inside the louver panel.

The BK manual blowerand the BKTthermostatically-controlled blower have an ON setting and an OFF setting. The blower will only run when the switch is in the ON position. In the OFF position, the blower will not operate.

Note for BKT Only: If you are using BKT blower with optional thermostat (wall mounted or remote control) for the ﬁreplace, your ﬁreplace and blower will not turn on and off at the same time.The ﬁreplace may run forseveral minutes before the blower turns on. After the heater modulates to the pilot position, the blower will continue to run. The blower will shut off after the ﬁrebox temperature decreases.

The blower helps distribute heated air from the ﬁreplace. Peri- odically check the louvers of the ﬁrebox and remove any dust, dirt or other obstructions that will hinder the ﬂow of air.

INSPECTING BURNERS

Check pilot ﬂame pattern and burner ﬂame patterns often.

PILOT ASSEMBLY

The pilot assembly is factory preset for the proper ﬂame height. Alterations may have occurred during shipping and handling. Call a qualiﬁed service person to readjust the pilot if necessary.

The height of the thermopile must be 3/8" to 1/2" above the pilot ﬂame as shown in Figure 49. The thermocouple must be at a height of about 1/8" above the pilot ﬂame. The ﬂame from the pilot burner must extend beyond both the thermocouple and thermopile.

If you pilot assembly does not meet these requirements:

•turn ﬁreplace off (see To Turn Off Gas to Appliance, page 24)

•see Troubleshooting, page 28

BURNER FLAME PATTERN

Burner ﬂames will be steady; not lifting or ﬂoating. Flame patterns will be different from unit to unit and will vary depending on instal- lation type and weather conditions.

If the vent conﬁguration is installed incorrectly, the ﬂames will lift or "ghost". This can be dangerous. Inspect the ﬂames after instal- lation to ensure proper installation and performance.

Figure 50 shows a typical ﬂame pattern.

If burner ﬂame pattern differs from that described:

•turn ﬁreplace off (see To Turn Off Gas to Appliance, page 24)

•see Troubleshooting, page 28

(V)VC42P SERIES, (V)VC42N SERIES specifications

The Desa (V)VC42P and (V)VC42N Series are advanced solutions in the HVAC and thermal control industry, designed to provide efficient climate management for various applications. These series are noted for their commitment to performance, reliability, and energy efficiency, making them popular choices among users looking for modern heating and ventilation systems.

One of the main features of the (V)VC42P and (V)VC42N Series is their state-of-the-art variable speed technology. This technology allows the units to adjust their output based on the specific heating or cooling needs of a space. By operating at different speeds, the systems can maintain a more consistent temperature while using less energy compared to traditional fixed-speed systems. This leads to significant cost savings and enhanced comfort for occupants.

Additionally, both series incorporate advanced control systems that can be easily integrated with smart home technologies. Users can remotely monitor and adjust their HVAC systems via mobile applications or voice-activated devices, facilitating greater control over their indoor climate. This compatibility with smart technologies not only enhances user experience but also contributes to energy conservation efforts by allowing for better management of usage patterns.

Another characteristic of the Desa (V)VC42P and (V)VC42N Series is their robust construction and design. Built with high-quality materials, these units demonstrate durability and reliability over time. The compact design of these systems allows for flexible installation options, making them suitable for various residential and commercial environments.

Moreover, the series prioritizes low noise operation, ensuring that the units run quietly without disturbing the peace in homes or workplaces. This feature is particularly essential in settings where noise control is critical, such as in offices, schools, or healthcare facilities.

In summary, the Desa (V)VC42P and (V)VC42N Series stand out in the HVAC market due to their variable speed technology, smart home compatibility, durable construction, and low noise operation. With their innovative features and characteristics, these systems are well-equipped to provide effective and efficient climate control solutions tailored to modern living and working environments.
