RADCO BURNERS FOR VENTED NATURAL GAS LOGS

AIR FOR COMBUSTION AND VENTILATION

WARNING: This appliance shall not be installed in a con- fined space or unusually tight construction unless provisions are provided for adequate com- bustion and ventilation air. Read the following instructions to in- sure proper fresh air for this and other fuel-burning appliances in your home.

Today’s homes are built more energy effi- cient than ever. New materials, increased insulation, and new construction methods help reduce heat loss in homes. Home owners weather strip and caulk around windows and doors to keep the cold air out and the warm air in. During heating months, home owners want their homes as airtight as possible.

While it is good to make your home energy efficient, your home needs to breathe. Fresh air must enter your home. All fuel-burning appliances need fresh air for proper com- bustion and ventilation.

Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances draw air from the house to operate. You must provide ad- equate fresh air for these appliances. This will insure proper venting of vented fuel- burning appliances.

PROVIDING ADEQUATE VENTILATION

The following are excerpts from National Fuel Gas Code. NFPA 54/ANS Z223.1, Sec- tion 5.3, Air for Combustion and Ventila- tion.

All spaces in homes fall into one of the three following ventilation classifications:

1.Unusually Tight Construction

2.Unconfined Space

3.Confined Space

The information on pages 4 through 6 will help you classify your space and provide adequate ventilation.

Unusually Tight Construction

The air that leaks around doors and win- dows may provide enough fresh air for combustion and ventilation. However, in buildings of unusually tight construction, you must provide additional fresh air.

Unusually tight construction is de- fined as construction where:

a.walls and ceilings exposed to the outside atmosphere have a con- tinuous water vapor retarder with a rating of one perm (6x10-11kg per pa-sec-m2) or less with open- ings gasketed or sealed and

b.weather stripping has been added on openable windows and doors and

c.caulking or sealants are applied to areas such as joints around window and door frames, be- tween sole plates and floors, be- tween wall-ceiling joints, be- tween wall panels, at penetra- tions for plumbing, electrical, and gas lines, and at other openings.

If your home meets all of the three criteria above, you must provide ad- ditional fresh air. See Ventilation Air From Outdoors, page 6.

If your home does not meet all of the three criteria above, proceed to De- termining Fresh-Air Flow For Log Set Location, page 5.

Confined and Unconfined Space

The National Fuel Gas Code (ANS Z223.1, 1992 Section 5.3) defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space and an unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with the space in which the appliances are in- stalled*, through openings not furnished with doors, are considered a part of the unconfined space.

This log set shall not be installed in a con- fined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air.

*Adjoining rooms are communicating only if there are doorless passageways or ventila- tion grills between them.

CPVSR18, and CVDR30, CPVSR24, CVSR24, CVDR24 specifications

Desa CVSR18, CVDR18, CVDR24, CVSR24, and CPVSR24 are a range of advanced heating solutions designed for various industrial and commercial applications. These systems combine a sophisticated blend of technology, efficiency, and ease of use, making them ideal for maintaining optimal thermal comfort.

The CVSR and CVDR series feature a unique vertical design that maximizes space efficiency while ensuring powerful heating capabilities. The model names indicate their heating capacities, with CVSR18 and CVDR18 offering output ratings of 18 kW, and the CVDR24 and CVSR24 providing a robust 24 kW. This scalability makes them suitable for a wide variety of environments, from large warehouses to smaller industrial facilities.

One of the key characteristics of these units is their high efficiency. Employing advanced combustion technology, the Desa heating systems reduce energy consumption while delivering superior heating performance. This not only translates to lower operational costs but also contributes to a reduced environmental footprint, aligning with contemporary sustainability goals.

The CVSR series utilizes a sealed combustion design, meaning that air is drawn from outside the building for combustion, improving indoor air quality and comfort. Meanwhile, the CVDR variants are designed for direct vent applications, allowing for flexible installation options. The direct vent feature ensures that exhaust gases are effectively expelled outside without interfering with indoor air circulation.

In addition to their energy efficiency and innovative design, the CPVSR24 model stands out due to its enhanced control capabilities. It includes smart technology integration that allows for remote monitoring and management, offering users greater control over their heating systems. This feature is particularly beneficial for businesses seeking to optimize operational efficiency by adjusting heating output based on real-time conditions.

Another notable aspect of these models is their durability. Constructed with robust materials, the Desa models are designed to withstand harsh operating conditions. Regular maintenance is made straightforward, ensuring longevity and reliability in performance.

Overall, Desa CVSR18, CVDR18, CVDR24, CVSR24, and CPVSR24 represent a comprehensive suite of heating solutions that prioritize performance, convenience, and sustainability. Their innovative features make them a strategic choice for those looking to enhance their heating systems while minimizing energy consumption and environmental impact.
