DUCTING MUST CONFORM TO LOCAL CODE MATERIALS AND
300 CFM MINIMUM
IMPORTANT: SAVE FOR LOCAL ELECTRICAL INSPECTOR'S USE
•DUCTING A
PERFORMANCE.
•AFTER READING THESE INSTRUCTIONS PLAN THE DUCT RUN.
•USE THE 'DUCT LENGTH CHART' TO FIND THE EQUIVALENT LENGTH OF THE RUN.
•SHIFTTHE BLOWER TO 'HIGH RANGE' IF INDICATED (DONE BY SNAPPING THE
'RESTRICTER RING' OUT OF THE BLOWER INLET), BE SURE BLOWER IS
NOT RUNNING.
•INSTALL THE DUCT HARDWARE.
•ENJOY GRILLING AND COOKING AT ITS FINEST!
THIS UNIT IS RATED AT 60 FEET OF STRAIGHT DUCT
LOW RANGE IS UP TO 30
IMPORTANT
GENERAL CONSIDERATIONS:
1.Use 6" diameter round or 37/4"x 10"rectangular only, except as follows: For Electric Models, 5" diameter round May be used for venting straightout the back of the rangeand directlythroughthe wallfor 10feetor less. For Gas Models with Electric Ovens, 5" diameter roundMust be usedif the ductlengthis 10feet or less.
2. Do notuse 5" elbowsexceptin a 5" system.Instead,use a 5"to 6"transitionfollowedby a 6" elbow,or a 5"to 31/4,,
x10"elbowtransition,
3.Usequalitymetalduct of at least26 gaugegalvanizedor 24gaugealuminum. Inferiorqualitypipeand fittingscan cause up to twice the restrictionshown and is a poor value. See box on page 4 for
ing. Local codes may require a heaviergauge material or restrictPVC.
4.Distancebetweenadjacentfittings (elbows,transitions, etc.) shouldbe at least 18".Thefartherthebetter.Closer distancepromotesturbulencewhich reducesairflow,
5. The numberofdownstreamelbowsor transitionsshould belimitedto three.The initial 5"to 6" straighttransition,if used,neednot becounted in this number.
6. Handmadecrimpsare likelyto cause restrictions.
7.If an alternatewall or roof cap is used, be certain duct sizeis notreduced,andthat thereis a backdraftdamper.
It is best to use listed caps to be certain of proper performance.
8.Thermalbreaks:Inareas ofextremecoldweather,it may be necessary to provide a short length of nonmetallic ductas closeto the wall as possible,to preventconduc- tJonalong themetaJduct.
9. High altitude installations: It is advisable to reduce allowableductrun by 20%.
10. Followthe duct calculation on page 2 carefullyfor best performanceand satisfaction.
