Note: Untwist the
pipe while extend-
ing it, to achieve
full 30’ length.
OR
*LINK-DV30B/LINKSQ-DV30: This installation may perform better and allow less cold air infiltration in
negative pressure settings.
**LINK-DV430B/LINKSQ-DV4-30:
• This installation may be more susceptible to cold air infiltration and the effects of negative pressure
on the appliance’s performance.
• Depending on the chimney cleanliness, consider using the full length intake so as to lessen
the possibility of sense rod contamination and flame rectification issues.
Note: Untwist the
pipe while extend-
ing it, to achieve
full 30’ length.
