1. Remove the wire on TH or HOT of gas valve and connect it on #1 on UC1 terminal block.
2. Connect #2 on UC1 terminal block to TR or Common.
3. Connect #4 on UC1 terminal block to TH or HOT on gas valve.
4. Connect 115 VAC supply voltage to L & N terminals on UC1. Installer must supply overload and disconnect protection.
5. Crimp ground wire to grounding spade in SS2 electrical box.
6. Make sure RED voltage jumper on UC1 is on 24V or 115V depending on control voltage.
NOTE: If burner safety control goes out on lockout, the SideShot will continue to run as long as a call for heat is present.
DRAFT ADJUSTMENT PROCEDURE FOR OIL EQUIPMENT
The SS2 Vent system will properly vent a wide range of BTU/hr. input capacities. To compensate for different burner capacities, vent connector
lengths, types and sizes, it features a draft adjustment located on the back of the venter assembly. Turning this draft adjustment knob clockwise will
increase draft and raise the BTU capacity. Turning the knob counter-clockwise will decrease draft and lower the BTU capacity. The SS2 is factory set
for the highest draft (BTU capacity).
IMPORTANT:
Before proceeding, close all windows, doors and fireplace dampers. Turn on all appliances in the structure that exhaust indoor air such as clothes
dryer, exhaust fans, range hoods, bathroom and whole house exhaust fans. Failure to perform the draft adjustment procedure may cause a poor vent
system installation possibly resulting in fire, carbon monoxide poisoning, explosion, personal injury or property damage.
1. Insert a stack thermometer into the vent pipe as close as possible to the SS2 inlet. NOTE: plug hole when finished with installation.
2. Adjust barometric draft control to the minimum or least draft setting.
3. Place the heating system into operation. NOTE: There will be a slight pause between the venter operation and the burner operation. A Venter pre-purge
of up to 35 seconds may also be selected. See “Pre / Post-Purge Settings” on page 5.
4. Continuously monitor the over fire draft and adjust the SS2 draft adjustment knob to maintain a reading of
-.02 to -.03” W.C.. When the flue gas temperature at the venter inlet has stabilized make any final draft
adjustment necessary to maintain a reading of -.02 to -.03” W.C.. IMPORTANT: If a minimum of -.02” W.C.
cannot be obtained with the SS2 draft adjustment knob turned fully clockwise and adjust barometric damper
closed “more draft” until a reading of -.02” W.C. is obtained.
5. Perform a smoke test and make any adjustments to the burner air shutter and venter draft adjustment to arrive at
a trace of smoke (between 0 and 1) at a minimum over fire draft of -.02” W.C..
6. Perform a CO2 test at the same location as the smoke test. Reduce the CO2 1% to 2% by opening the burner air
shutter. Recheck over fire draft and increase venter draft or adjust barometric damper closed “more draft” if
necessary to maintain a minimum of -.02” W.C..
Do not allow heating system to run at less than a -.02” W.C. over fire draft or at a CO2 level that is less than a 1% reduction from the value measured at
a trace of smoke and a -.02” W.C. over fire draft. If these parameters are unobtainable, contact Tjernlund at 1-800-255-4208 for Technical Assistance.
7. Remove the call for heat from the heating system. NOTE: The SS2 will run in post-purge mode which is factory set at 2 minutes and adjustable
up to 16 minutes. Allow the system to cool down to ambient room temperature.
8. Restart the heating system.
