Direct-vent and B-vent work, step by step
Restrictor settings after a route change
On certain direct-vent models, a flue restrictor inside the appliance is positioned to suit the vent's vertical rise. One manual links each vent configuration to a restrictor position in a chart.
If the vent route has been changed, the restrictor may no longer match it. We check the setting against the manual for the installed route and adjust it where the manual allows. A wrong setting can make the fire look poor or behave differently from the manual's description, which is easily mistaken for an appliance fault.
Wind, downdrafts and the vent cap
One vent maker explains that a cap resists rain, debris and birds and limits the effect of wind on the vent, including downdrafts from wind striking it directly. The same maker adds that no cap can overcome a zone of high pressure around the termination or low pressure inside the house.
If your fireplace behaves badly only in certain winds, mention the pattern. We check the cap and the termination position against the manual's rules. Where the position itself sits in a poor spot, we explain the options, including relocating the termination within the vent tables.
Checking vent work someone else did
If your vent was repaired or extended before and the fireplace has not behaved well since, tell us what was done. Mixed parts, unlisted caps, missing supports or a route outside the tables are common findings after hurried work.
We compare the installed vent with the appliance manual and the vent instructions and explain any differences without judging whoever did the work. The estimate covers what is needed to bring the vent back to its listed arrangement, section by section, so you can see where each cost comes from.
Vents passing through upper floors
A vent that rises through upper floors passes through ceilings and floors that each need a firestop, and it may run through closets or chases on the way. Each crossing is a place where clearances can be lost during later work.
We follow the route floor by floor where access allows and check each crossing for its firestop and clearance. Where the vent runs inside a chase, we look at how the chase is blocked. Crossings we cannot reach are noted, and access to them is offered as a separate item.

Questions on gas vents, answered for Biscayne Park
Can a gas fireplace vent through an old masonry chimney?
Some appliances are listed to vent through a liner or gas vent inside a masonry chimney. Before the connection, the fuel gas code calls for the chimney passage to be checked for obstructions and cleaned if wood or another solid fuel was burned in it. Insert liners are handled under the insert service.
Can Type B vent be used on any gas appliance?
No. The vent maker lists Type B vent for appliances with draft hoods and others listed for Type B vent. It is not for appliances that can be converted to burn solid or liquid fuels. The appliance manual confirms which vent applies.
Can a new window or door near the termination cause a problem?
It can. Terminations need clearances from openable windows and doors, and a new opening can fall inside them. We measure the relationship against the manual and explain whether the termination or the opening needs to change.
