LINK-DV30B/LINKSQ-DV30: This installation
may perform better and allow less cold air in-
filtration 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.
