Tjernlund DC6 Single Action Draft Control
Single Acting Galvanized Draft Control For Oil, Solid Fuel and Fan Assisted Gas BurnersHeating appliances are designed to operate with a consistent draft. Chimney configurations, mechanical draft fans and weather can cause draft fluctuations. These fluctuations result in inefficient combustion and more frequent service calls. Draft controls regulate the airflow through a chimney or vent. By diluting the chimney/vent draft with varying amounts of room air they maintain the draft at a heater's flue outlet within a consistent, safe and efficient range. This single acting control is made of galvanized steel for low maintenance and corrosion resistance. It has integral anchor points and self- aligning, self-centering rocker bearings for long lasting service. A cushioned stop minimizes rattle and noise. Adjustment is easily accomplished by moving counter weight on outside tab.$102.00 -
Tjernlund MAC-4E
Enables Appliances to be Interlocked in Conjunction with UC1 universal controlThe MAC4E is used in conjunction with the UC1 Universal Control to interlock up to four additional 24 VAC, 115 VAC or millivolt (Dry Contact) controlled appliances. It activates the Venter through its connections to the UC1 and in turn relies on the UC1 Fan Prover safety circuit (P1 & P2) to allow its interlocked appliances to operate. Any pre/post-purge settings on the UC1 will be defaulted to the MAC4E. Two LEDs for each appliance interlock block are provided on the MAC4E. LEDs #1, 3, 5, 7 (AMBER) shows an appliance call for heat. LEDs #2, 4, 6, 8 (GREEN) shows that the burner is approved to fire after the Venter Fan Prover safety circuit through the UC1 is completed. The MAC4E also has an LED #9 (RED) which means power is supplied to the MAC4E through the UC1.$596.00 -

Tjernlund Gas Pressure Switch
Gas Pressure SwitchThe gas pressure switch is mounted on the casing of the water heater adjacent to the heater's thermostat/gas control valve. It should be mounted close enough so that the supplied 1/4" tubing will reach from the gas pressure switch fitting to the thermostat/gas valve pressure tap port. The two provided screws are self-tapping and drilling. The screws do not require the use of a drill and their 1/2" length assures that the inner tank will not be penetrated$86.00 -
Tjernlund Spill Switch Kit
Gas Spill Switch KitThis Safety Interlock System may be used on conventional chimney or Power Vented appliances equipped with a draft hood, draft diverter or draft control. It's purpose is to provide a means for appliance shut-down in the event of flue blockage or down drafts. The Spill Switch circuits are “normally closed” and will not affect normal appliance operation. When concentrated spillage of combustion gases occurs from the draft hood, diverter or barometric control, the Spill Switch circuit will open preventing burner operation. ***WARNING*** The 24SP200 Flue Gas Spillage Sensing Kit is designed to alert the user to a potentially hazardous condition. It is not designed to, and cannot replace regular chimney inspection, appliance servicing and combustion testing. DO NOT USE THE 24SP200 AS A SUBSTITUTE FOR PROFESSIONAL APPLIANCE MAINTENANCE.$84.00 -
