Installation

Bolt the Automatic Draft Control through the 1/2 in. hole in the center of the bottom door. Be sure to hold the Draft Control straight while tightening. Feed the two wires from the draft motor through the flexible conduit and a 90˚ fitting. Secure the fitting to the draft motor and that end of the conduit at this time. Check the flapper door on the Automatic Draft Control assuring that it moves freely.

Install the (3) brass coil spring handles onto the door latches and the shaker handle. Start the spring handle onto the shaft and twist it counter- clockwise while pushing.

Aquastat Installation

(See optional items, page 7) Lay the din rail on a flat surface, with the flat side down. Secure one end clamp, on the left side. Slide the A350 controller onto the rail from right to left until it is against the end clamp. Slide the Y350 onto the rail and guide the plug-in connector, joining it to the A350. Next, install the S350, again, guiding the plug-in connector carefully. Install the other end clamp to the right side of the din rail. Remove the covers from all three controls by loosening four screws each. Install the terminal box to the controls using (3) chase nipples and locknuts, supplied with the kit. Using the four holes in the terminal box, mount the terminal box and controls to the boiler sheet metal side as shown in Fig.1. Using (2) #8-32 nuts, install the terminal block onto the studs located inside the terminal box.
