Terminology:
The manual defines key terms:
- CSA: Canadian Standards Association - International
- UL: Underwriters Laboratories
- CUL: Underwriters Laboratories Canada
- Pilot Thermocouple: A bimetal probe generating electrical current when heated.
- Oven Pilot: The oven pilot burner that continually heats the thermocouple and provides ignition for the main oven burner.
- Block with Main Burner Orifice: A precision drilled component metering gas flow to the main burner.
- Manifold: A pressurized tube or pipe supplying gas to the top and oven burner valves.
- Oven Thermostat: Controls oven temperature and supplies gas for pilot and oven burners.
- Piezo Igniter: An electromechanical device for igniting top burners.
- Spark Igniter: A battery-operated device for igniting top burners and oven pilot (requires 1 AAA battery).
- Regulator: A valve reducing propane tank pressure to operating pressure.
- Thermal Bulb: Located in the oven, attached to the thermostat, containing thermal fluid to open and close the thermostat based on set temperature.
- Yellow Tipping: Burner flame with yellow tips due to inaccurate gas/air mixture, incorrect placement, or restriction of orifice and venturi tube.
Manifold Identification:
Three types of manifolds are identified with descriptions and usage timelines:
- Sabaf (Round) Manifold with plug-in thermocouple: Original mercury-free system (2004-2006), used concurrently with BSI (late 2006-early 2009), and exclusively in sealed burner & glass top models since early 2009. Individual components available separately.
- BSI (Square) Manifold: First used late 2006, concurrently with Sabaf (late 2006-mid 2009), exclusively on conventional burner models (mid 2009-mid 2011), and concurrently with Copreci (mid 2011-present). All components available as an assembly.
- Copreci Manifold (Round) Manifold With screw in thermocouple: Initial release mid 2011, used concurrently with BSI on conventional burner models (January 2012-present). All components available as an assembly.
Usage Features:
- Installation Instructions: Detailed steps for installing Slide-In Cooktops, Ranges, and Drop-In Cooktops, including cabinet preparation, gas connections, and securing the unit. Emphasizes sealing cabinet openings around gas lines and proper ventilation to prevent negative or positive air pressure issues.
- Operating Instructions (Top Burners):
- Identify which knob controls which burner.
- Depress knob and turn counter-clockwise to "Lite" position.
- Verify sufficient gas supply; air in gas lines can delay ignition.
- Do not attempt to light more than one burner at a time.
- Use a long match for "M" models.
- For "E" models, rotate piezo knob clockwise rapidly.
- For "S" models, depress the push-button battery-powered spark igniter.
- If a burner extinguishes, turn gas off, wait 5 minutes, then relight.
- Turn control knobs to "OFF" when not cooking.
- Operating Instructions (Oven):
- Oven pilot must be lit before the oven burner operates.
- Lighting Oven Pilot: Ensure all valves are "OFF," main gas supply is on. Open oven door and check for gas odor. If no odor, turn knob to "Pilot" position, "Push In/Lite Pilot." Light pilot with a match, hold knob 5-7 seconds. Release knob; pilot should stay on.
- Operation of Oven Burner: Turn oven control knob counter-clockwise to desired setting. Burner will come on and stay on until desired setting is reached, then flame size will decrease to maintain constant temperature.
- Shut Off Oven Burner: Turn oven control knob clockwise to "Pilot On" position.
- Shut Off Oven Pilot: Slightly depress knob and turn to "OFF."
Maintenance Features:
- Troubleshooting Guide: Provides solutions for common problems:
- Oven: Pilot won't light (insufficient gas supply/pressure, restriction), pilot won't stay lit (defective thermocouple, pilot plunger not engaged, defective magnet, micro-switch not engaged), main burner won't light (no gas flow, air shutter incorrect, restriction), main burner flutters (air shutter incorrect, low gas pressure), pilot goes out during baking (defective pilot burner, defective thermostat, restricted tubing), poor baking results (oven not preheated, poor air circulation, sensing bulb incorrect, thermostat out of calibration).
- Range Assembly: Oven door won't stay closed (hinge spring too loose, hinge foot not installed correctly), range top won't stay latched (latch improperly adjusted, range installed incorrectly).
- Slide-In and Drop-In Cooktop: Burner won't light (clogged port, insufficient gas pressure), burner won't light with piezo (improper installation, defective electrode, defective piezo), burner flame uneven/too small (clogged port, insufficient gas pressure), flame lifts off burner (propane pressure too high), yellow flame (incorrect burner tube to orifice holder alignment).
- Range Door Removal Instructions: Detailed steps for removing and reinstalling the oven door using pins to lock the hinges.
- Warranty Information:
- Two-Year Limited Warranty: Covers defects in material and workmanship under normal use and maintenance for two years from the date of purchase. Porcelain parts are warranted as commercially acceptable only as of the date of manufacture.
- Proof of Purchase: Required (Bill of Sale or other payment records).
- Service & Reimbursement: Suburban will replace defective parts and pay a warranty service allowance to recommended service centers. Freight, shipping, and delivery costs are the owner's responsibility.
- Owner's Obligation: Return appliance/parts for examination, including model/serial number plate.
- Warranty Service Contact: Contact nearest recommended Suburban Service Center or Suburban's Service Department at 423-775-2131 for authorization.
- Limitations: Warranty does not cover normal maintenance, initial checkouts, faulty installation, cosmetic damage, operational failures due to loose wires/dirt/improper gas pressure, cleaning/adjustment of components, costs to access appliance, parts not supplied by Suburban, freight charges, damage from misapplication/abuse/unauthorized alteration/improper service, altered/defaced serial numbers, installations outside Continental U.S.A./Alaska/Hawaii/Canada, damage from natural events, or consequential damages.
The manual emphasizes the importance of understanding the appliance's sequence of operation and component functions for effective troubleshooting. It also highlights the critical role of proper installation, including gas pressure and compliance with physical installation tolerances and clearances, and the necessity of regular maintenance to prevent component breakdown.
