A double-acting control for gas-fired furnaces and boilers is widely used for conversion burner installations, gas draft-induced appliance operation with mechanical draft inducers or sidewall power venters. It is also recommended for use on gas atmospheric appliances where a draft hood cannot be installed and can improve combustion stability and draft on many gas atmospheric installations with venting problems. The MG-1 provides precise, accurate control of drafts at levels higher than permitted by a standard draft diverter, which is a frequent requirement with gas. Because it is double-acting, it opens out to relieve positive vent system pressures as low as 0.01" draft adjustments using weights are simple and accurate from 0.01 - 0.1".

Gas and oil heating appliances generate heat through the combustion of fuel. The heat is transferred through the heat exchanger and distributed to the conditioned space. The products of combustion, however, must be vented safely out of the structure. In a conventional chimney, venting is achieved by the natural lifting action of the hot combustion gas. New, efficient systems absorb more of the heat in the heat exchanger and produce lower temperature vent gas. Lower temperature gas does not rise as quickly or as reliably as in older, less efficient systems. Power venting or sidewall venting is more economical and safer than chimney venting. A power venter uses a motorized blower to vent the products of combustion. A power venter is interlocked with the appliance to ensure that proper draft is achieved before the appliance burner is activated.

Tjernlund The SideShot models SS1 and SS2 SideWall Vent Systems include the UC1 Universal Control for increased safety, performance and reliability. Designed for oil fired heating equipment or a deluxe gas vent system. Patented vent termination propels flue gases at high velocities away from the building exterior, a necessity when venting oil fired equipment. Both models can be installed with zero clearance to combustible materials and have stainless steel construction in critical areas. Factory wired safety and operating controls allow simple interlock with any burner. The new model SS2 features a self-cleaning stainless steel, backward inclined impeller and sealed ball bearing motor for virtually maintenance free installations. Ultra-fine draft adjustment and slide-out access to all internal components. Easy multiple appliance interlocks with our MAC Series multiple appliance controls.

Use to side wall vent non-condensing oil fired boilers, water heaters and furnaces that otherwise would require a conventional roof top terminated chimney
• Built-in interlock control with redundant high limit safety switch interfaces easily with thermostat, aquastat or primary controls
• Adjustable pre and post purge timing and easy fault code retrieval
• Stainless steel construction in all critical components including outdoor terminus
• Patented design jets flue gases away from the outside wall to eliminate potential staining of siding
• Slide out service drawer and material handling stainless steel impeller

The ZD is a power close and spring open damper. It has a 24-volt motor used to control circulating air in HVAC systems and used when a normally-open damper is required. The ZD is typically used with the TrueZONE and other electronic zoning systems.

• Mechanical visual position indicator for damper status
• Solid construction using extruded aluminum frame and blades
• Parallel blade design for low leakage performance
• Simple, easy-to wire, two wire installation with a third wire option M4 for LED open only light
• Reliable, strong, 24 volt spring return motor
• Fail-safe, normally open operation
• Ordering instructions: order ZD (dimensions 1) x (dimensions 2), (motor is always mounted on dimensions 2 side) for example, ZD10x8 is a 10 x 8 Inch damper with the motor on the 8 Inch side, but a ZD8x10 is an 8 x 10 Inch damper that has the motor on the 10 Inch side
• Damper can be installed in any orientation (mounting side can be on either the bottom or the side of the duct)
• Motor or actuators mounting - side or top
• 30 sec power closed/10 sec spring return
