Resideo Y8610U Intermittent 1 or 2-Rod Natural Gas/LP Pilot Retrofit Kit for Gas-Fired Atmospheric Furnaces, 24 VAC

• Intermittent pilot retrofit kits save energy by converting atmospheric standing pilot systems to intermittent pilot
• Use with natural or LP gas
• Provides 100% pilot gas shutoff if pilot fails to light, after 6 min delay, trial for ignition is repeated
• Ignition trail/delay sequence is repeated until the appliance lights or call for heat is removed
• 2 sec flame failure response time
• 0 or 30 sec pre-purge time
• Ignition sequence - continuous retry, after trial for ignition, pilot gas shuts off for 5 min then another trial for pilot ignition takes place
• Typical gas control - VR8204, VR8304
• Ignition source - internal high voltage spark generator
• Ignition trials to lockout - continuous retry
• 1 amp pilot, 2 amp at 24 VAC maximum valve load
• Q345, Q3451 typical ignition hardware

ZD12X12TZ Honeywell Zone Damper Bottom Mount 12" x 12" Power Close & Spring Open 24 VAC 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
• 90 deg angular rotation
