Tjernlund SS1R SideShot (Discontinued) with UC1 Universal Control (Version X.04) 8504117 Rev 02/04 - Manual (Page 5)

SS1-R WITH INTEGRAL UC1 UNIVERSAL CONTROL BOARD FEATURES
# 1. Power supplied by board. Do not supply power to this area or control damage may result.
# 2. Do not supply power to the appliance interlock block with the call selector in the “DRY” position.
Control damage may result if power is supplied.
# 3. Circuit protection must be provided by the installer. 16 Amps is the maximum current allowed for this device at terminal L.
VETI
A 15 Amp circuit breaker is recommended.
VETI I A
PRE / POST PURGE AND PROVER STATUS CHECK DIP SWITCH SETTINGS
Remove power to SS1-R and heating equipment when installing, servicing or changing dip switch settings. Failure to do so may result in
personal injury and/or equipment damage. LED #5 (RED) should not be on if 115 VAC supply power is removed from the control.
Pre-purge
Used for longer vent runs to get draft fully established throughout the vent system prior to burner ignition. Also beneficial for nega-
tive pressure prone environments. IMPORTANT: Nuisance equipment lockouts may occur if our pre-purge is running in conjunc-
tion with and is longer than any equipment timing circuit. Pre-purge settings must be shorter than burner control lockout time
unless wired prior to burner control timing circuit (i.e. aquastat / thermostat).
Post-purge
A Venter post-purge has been factory set at 2 minutes. Confirm that dip switch #5 is in the up or "on" position. Oil fired equipment
requires that the post-purge be long enough to eliminate post cycle nozzle drip odor. A longer post-purge may be necessary for
longer vent runs or high heat retention, refractory lined combustion chambers.
